Wow, what a year this has been. Both at the same time, I seem to have learned so much and yet so little. I’ve made a lot of new contacts in the world of networking both online and in that scary thing called real life. It makes sense for me to have an end of year review.
Back in January, I made one of my first posts outlining what I hoped to achieve by the end of 2012 from a certification point of view. The four items listed were:
So how did those targets match up with my achievements? Well, I passed the ROUTE and TSHOOT exams to gain my CCNP which made me about as proud as when I got my 2003 MCSE:Security some years back. I set out to do the CCDA and after going through the INE video series and half of the Cisco Press book, I found the material to be very dry. Rather than pushing on, I decided to shelve the CCDA for now, quite possibly returning in the future to complete it.
I do a fair amount of my day-to-day work on Cisco ASAs so it made sense at that point to start working towards the CCNP Security. This has a prerequisite of the CCNA Security, which I attained in October, letting me tick number 4 off the list. I’ve also since passed the first of the four CCNP Security exams, SECURE and am now studying towards the FIREWALL exam.
So all in all, not too bad. I dropped the CCDA but managed another exam in its place and will return to the CCDA once I get a bit more network design experience under my belt. I think it has been very useful to post my goals for this year. I found that referring to it every now and again gave me the boost in motivation required to keep on track.
Outside of the realm of certification, I have also had the good fortune to start expanding my existing knowledge on topics such as Wireshark, NMap, Solarwinds, UCS, VSS and many others. I fully intend on casting my knowledge net much further over the next 12 months.
As regards to my blog, I would ideally have liked to post far more often but when the priorities have been lined up, blogging hasn’t been at the top unfortunately. I am hoping to post more frequently next year, quite probably starting 2013 off with another ‘resolutions’ post to keep me right.
In the new year, I will probably be changing the theme of the site. When I added it, I thought it looked a bit different from a lot of others but after 12 months, it looks a bit dark to me and could do with brightening up a bit. Depends on me finding something I like. On top of that, I’ve just updated WordPress and the banner graphic is out of sync for some reason.
Finally, I would like to thank everybody who has spent time coming here to read my musings. I hope you found something that was of use to you or at least put a smile on your face. Please feel free to contact me at firstname.lastname@example.org if you have any requests for posts, suggestions for the site or simply to ask a question or touch base. I would also like to thank everybody on Twitter\LinkedIn\etc. who has helped me out\engaged with me along the way. It’s great to know there is a large community of helpful and witty people out there.
Happy holidays to you all and here’s hoping we all have a great 2013!
In part 1 of this article, I give a little background of how my home network has previously been set up. In part 2, I go through the plan of upgrading my home network and how that plan was implemented.
I’ve lived in my current house for six years. It’s an old farmhouse out in the country and my wife and I fell in love with it as soon as we saw it. I had asked the previous owner if she could get ADSL and she reported she hadn’t signed up but was under the impression it was available. Upon moving in, I signed up with an ISP who thought it should be possible, but alas upon installation of the router and filters, it wasnt to be. I had British Telecom engineers out to my house, their Higher Level Complaints team on the phone frequently but it just boiled down to me being too far from the exchange. This was rubbed in further by houses on each side only a 1/2 mile away that enjoyed ADSL Internet access. BT’s line routing policy meant I was stuck.
So I used dial up for about a year and nearly went insane due to having to take this step back to the (1st world) dark ages. Migrating 750 MS Exchange users to a new domain via Powershell over a high latency\low bandwidth dial up VPN connection is about as much fun as sticking pins in my eyes. On top of the weekend overtime I was putting in, I was also on the on-call rota for one week in six. More often than not, I’d find myself driving around to my parents who live a couple of miles away to use their broadband if I thought the job would take more than 15 minutes. RDP over dial up is appalling more often than not. When you need to RDP on to your jump box via VPN to then RDP on the customer’s jump box to then RDP on to the server in question (I love customer’s requirements), a five minute job could literally take well over an hour.
I then heard about the Scottish Government stumping up a paltry £3.5M to fund it’s Broadband Outreach programme, to bring broadband to those that were currently unable to receive it for whatever reason. Enter me and about 10 neighbours of mine. I jumped at the chance to be our ‘cluster’s’ front man and was soon dismayed to find out that the final solution would be two way satellite, provided by Avanti who at the time didn’t have a great reputation. The fact that I spent every day under contract with them wishing I had an alternative should clarify if that reputation was founded or not. Quite frankly, they were appalling. The dish was almost the size of Jodrell Bank. The modem was the size of a DVD player and it had two thick strands of coaxial cable running to it via a hole in the wall. On a good day, the latency was 750ms. On a bad day, it simply didn’t work. It cost about £45 a month for a 2Mb\s connection which thankfully, my company stumped up the lion’s share. Something had to be done.
I had tried a number of different 3G mobile dongles from T-Mobile, Orange and Vodafone and all were worse than the satellite. Even walking around the house outside with my laptop made little difference. My house has 12-18″ thick walls in places so I was still willing to have something mounted outside with a lead coming back in. After about 3 years of putting up with the satellite, I decided to look at the problem again, this time reviewing 3’s website, another mobile provider who were one of the first to market with 3G in the UK. I checked their site which claimed I could get 3G at my postcode. I decided to give their PAYG package a ‘low risk’ try out. When I got the dongle home to test, I got the same lame connection. But when I walked around the house with this one, I would find some sweet spots where the latency dropped to 70ms and I could get a solid 1Mb\s up and down speed! This was massive progress, despite some of my colleagues from the big smoke advising me their home connection had just been upgraded to 100Mb\s. I did a good selection of testing, including my work VPN, YouTube, general browsing and a long lost art for me…online gaming using Call of Duty: Modern Warfare. All passed with flying colours and I signed up for a contract.
It is worth pointing out at this stage that my internal network was crappy too. Those hefty walls are great at stopping WiFi as much as 3G signals. When I got the MiFi device (a 3G modem and WiFi AP\router in one device), it was best placed in the main bedroom, plugged in for a stronger, more consistent signal and draped over the latch on the window. Unfortunately, the TV room is downstairs and at the other side of the house i.e. pretty much as far from the MiFi as possible. I bought a WiFi extender but it simply repeated the signal on the same channel and so, whilst it made the coverage better, it didn’t seem to improve connectivity if there were a couple of devices trying to connect at the same time. Access to the MiFi was affected with packet loss due to collisions\retransmissions. I needed a more resilient solution so I took a more holistic approach to my networking needs. In part 2 of this article, I outline the design I came up with and give some installation pictures. Hopefully, some people reading this might find some nuggets of inspiration. At the very least, I hope it puts a smug smile on some of the 100Mb\s+ brigade!
Need to go now, the electrician has just turned up to power up the loft.
I gave myself four targets for the year which I still think is more than achievable so let’s take a look at my half year review. I am glad to say that I have ticked numbers 1 and 2 off of the list to gain my CCNP at the half way mark and still have numbers 3 and 4 well within my sights. I think design skills are important to have, even if designing networks is only a small part of your job. If you know how networks should be put together, you are better qualified to point out where improvements can be made in existing networks. This allows you to go beyond simply fixing issues as they occur and approach troubleshooting as a continual improvement process. I am currently in my 2nd week of a two week holiday but fully intend on starting my CCDA studies before month end.
Regarding my other CCNA speciality, I have decided to go for the CCNA Security as the first step in my desire to get a highly job relevant CCNP Security at some point in 2013\14. I am also going to go back to basics in terms of routing and switching knowledge and start building up some study tools so that once I feel I am ready for the CCIE R&S, I will already have built up some momentum. By this time next year, I hope to have a fairly comprehensive flash card library and some expansive mind maps.
The reason for this brief post is mainly for my own motivation. Keeping track of your goals, changing them where required, adding new ones and ticking them off the list as you achieve them is a good way of staying motivated and keeping the momentum up. Without a review from time to time, you can find yourself drifting from your original goal with no real idea of what it is you want. I tend to review my goals much more frequently than every six months, usually every few weeks or if and when something happens which sticks a spanner in the works of some kind.
Before I go any further, this is my first post using Blogsy on the iPad so here’s hoping it publishes as expected.
I returned to work last week after a lovely beach holiday with the family, chilling out and catching some rays. I went in to the office on Monday with the full intention of putting a couple of ongoing issues to bed and taking note of the outstanding tasks that need addressing so that I could formulate a plan of attack.
Let me give you a little background to put things in perspective. I work for an ISP in the UK. I see my domain as a network engineer broken down in to four main areas. There is our core network, our access customers such as dial up, ADSL\SDSL, leased lines, MPLS etc, our hosted customers that reside in our different data centres and the management piece that encompasses all of these which includes logging, performance monitoring, security, configuration management, auditing, documentation and all that good stuff. Some of these things are missing, some are in place but all need attention to some degree at some location under my responsibility. I started at the company 4.5 years ago as a Microsoft engineer and those who have read my previous posts will know that I got my CCNA three years ago and made the fully fledged move to networking in November of 2011 so I am a relative noobie, despite hopefully being only a few weeks away from gaining a hard earned CCNP.
So back to my original tale of good intentions and their rapid evaporation. Thursday morning came around and I found that I had become increasingly annoyed over the week. Although most likely not true, it seemed that every time I logged on to a device to either make a change or troubleshoot an issue, I was finding trails of legacy config, standard practice being laughed at and very little in the way of an explanation of why certain quirks had been put in place. I’ve seen several network engineers come and go during my time with my current employer, with various skills and capabilities. The problem is that they have all left now. The current team include myself, who only really ‘looked behind the curtain’ at the end of last year and two others that have joined even more recently so I found myself from time to time playing the well known game of ‘blame the guy who has moved on’. Fair? In this case, absolutely. Helpful? Not one bit but I do believe that anybody putting a network infrastructure in place should leave enough documentation behind for another capable engineer to pick up and not only understand how that network is supposed to work but also why certain design decisions were made. I don’t think that’s a lot to ask for as a minimum. So as I drove home on Thursday evening, I found myself quietly seething about me having to pick up the crap left behind by others. This is nothing new in the world of IT though, or indeed in many other fields.
On Friday morning, I decided that I wanted to walk our core network to get a better grasp of how it ticks. I printed off a Visio diagram (as a side note and final moan, a diagram that I created six months ago as the existing one at that time was a mess and largely incorrect). My plan was to start at the edge where our little part of the Internet joins the big boys, work my way to the core and back up to our other edge (we are multihomed) one device at a time. This could take days or even weeks to do, depending on what depth I wanted to go to.
Only five minutes in to my first router and it hit me like a thunderbolt. I wasn’t shrugging my shoulders at the configuration that lay before me. This was now my network and it was mine to improve, tweak, fix and care for. I suddenly saw what was previously a daunting task as an amazing opportunity to improve my own knowledge, understanding and confidence as well as the network itself.
Slightly giddy, I opened an Excel spreadsheet and created a new tab for each core device and a general one to cover things not specific to any one device. I took a dump of the router’s config and started going through it line by line. Anything that looked wrong or didn’t make sense didn’t get me mad. It just got noted. Anything relevant to the Visio that wasn’t already on it got pencilled in for later. I had other tasks to do that day so only managed the one device but it felt very satisfying.
I now had a much clearer vision and a drive to see it through to completion. It all changed with a flick of a switch in my head labelled ‘attitude’. The same problems exist but now I own them, even embrace them and that means this is all going to actually be fun (my twisted sense of fun anyway). This could be the greatest training programme I ever go on…and I get paid for it!
One final thing to say. The title of this post may be slightly misleading to some. Don’t get caught up in the illusion that you really do own a network that you’ve invested time in, unless of course it’s your home network. What I’m saying is, don’t become that guy that keeps details to himself in order to give himself that false sense of job security. You are a facilitator. Share the knowledge so that others can add value too.
I recently posted at Packet Pushers about 10 key areas that people who work in IT should focus on to see improvements both in their working and personal lives. This post looks at the first of those areas, time management. To match the theme, I will make this post as short as possible so you can get on with the rest of your day.
There are countless books, websites, guides, courses, etc. that give you advice on how to improve your productivity. Some of these are very good, others less so. What most of them share in common is a toolbox of techniques to improve your time management. This post offers only three such tools that I use every day. I guarantee that if you condition yourself to use them every day too, you will find yourself getting more done. For those of you who are really busy, here are the three techniques, which I discuss further below:
4 Ds method
Very simple this one. Every evening before you go to bed, spend up to 10 minutes writing out a list of things you need to get done. How you break down the list is up to you e.g. one list for work, another for home. Take any of the big tasks and break them down in to smaller ones. Then prioritise them in a way that works for you e.g. tasks that must be done the next day, those that can wait till later in the week, etc.
Once you have your final list, broken down with enough detail to get you started at full speed and in order of priority, take the list to work the next day and start on the number one priority and get it completed before working on the next task on the list. Cross out each task as you complete it.
4 Ds method
This applies to any workflow that comes your way, whether it’s your helpdesk application, paper tray or email inbox. It’s a simple way to deal with anything that is going to use up some of your valuable time. The 4 Ds all do what they say on the tin. The explanations I give are from the point of view of an email that has just landed in your inbox, but you can apply, as stated above, to any incoming request for your time:
Deal. If this is a priority, deal with it right now. Do what is required, sign it off and move on.
Delegate. Send this onwards to somebody else who can deal with this. Only make a note if you need to chase it up yourself.
Defer. This one is critical. If you need to deal with it, but not just yet, move it to a ‘Defer’ folder and only look at this folder when you are going to deal with it. You must get out of the habit of looking at deferred items more than once before doing anything with them. That costs you a lot of time in the long run.
Delete. Just delete it and have done with it.
Distractions can easily suck up hours of your working day:
Meetings that you should not have been in
Meetings that go on for two hours with a five minute ‘useful’ bit
Telephone calls that match the two meeting points above
Gossip around the coffee machine\photocopier
‘Can you just take a quick look at this for me’….an hour later, you are still looking
Distractions such as those above and countless others eat in to your working day and indeed life in general. Learn how to deal with them in an assertive yet professional manner.
An example: I’ve said on many occasions that I am unable to make it to a meeting due to being busy on something else. When I read the meeting minutes later, I learn in less than five minutes what it took the attendees 90 minutes to find out. I try to only attend meetings where my input is necessary and even then, I can often give my input after the fact.
When you walk about the office, walk with pace. Not only do you get where you are going quicker but it makes it easier to get past that person who is always grabbing you for advice. When I make myself a brew in the kitchen, I take it straight back to my desk. I eat my lunch at my desk too.
If somebody keeps tapping you on the shoulder for help, rather than doing it for them, show them how to do it themselves, perhaps with a Wiki article or a process guide. Or send them a LMGTFY link. Or be honest and tell them that you are really busy now but if they send you the details, you will get around to it.
Of course sometimes it’s somebody senior to yourself who keeps sapping your time and if that is the case, refer them to your list of priorities for the day and ask them where their request falls on that list. It’s amazing how often they will concede that it’s not as important as first suggested.
Use each of these in conjunction with one another and really put effort in to each of them. It has been estimated that learning a new habit requires daily practice and takes about 2-3 weeks before it starts to feel natural. However, get started today and you will see results almost immediately. Let me know how you get on in the comments below or via email. I also have an upcoming post on how to make the most of your studying time that I have found not only lets me learn things quicker, but makes the topics sink in!
Finally, remember that on average, we have 450 minutes at work each day. Try to make every single one count and watch your productivity soar.
The dust has finally settled on Cisco Live London 2012, the vendors have moved on and the Ethernet and power leads ripped out. On the latter point, these were actually being pulled out as I walked out of the final session on the Friday. Well, they say that time is money.
On that very note, before I start to talk about the value of this event as I perceive it, let’s look at what the real costs are (and damn you WordPress image compression!):
This covers the event from Tuesday to Friday midday. Monday is a full day for those that wish to attend the technical seminars. I believe that there were 25 on offer this year and assume that they all cost the same as the one I attended at £475. All of these costs are excluding VAT. You get lunch provided on Monday through Thursday (with a packed lunch on the Friday) and there are snacks and drinks served at various times throughout the day, so you need to factor in evening meals, accommodation and travel costs in to the equation, although Cisco put on a number of parties in the evenings with food. It can all add up quickly. I was fortunate enough to get company sponsorship to attend and, as my company has a flat in the Shoreditch area of London, the costs to the company were in the region of £3000, including my expenses.
If you have to factor in a hotel which isn’t a flea pit, then suddenly you are looking at a ball park figure of £4000 for the week. Not a casual spend by any stretch of the imagination. Yet I spent not a penny of my own so my attempt to define the value of this event in terms of money might at first be pointless. Or would it? Surely I can (and I will as you’ll soon see), list what I see as the main benefits of attending this event and then summarise by saying, would I pay £4000 of my own money to attend. The problem with that is, I don’t have £4000 lying around spare so the answer would have to be no.
Let’s leave the financials out of the discussion for the moment and talk about the benefits of attending this event.
Meeting the vendors – the World of Solutions conference hall allowed many different vendors to set up their stall and tell me why their products were unlike anything else on the market. OK, so there will always be a biased pitch but I am fairly immune to that kind of thing (or at least know when I’m letting myself be swayed) and am happy to ask probing questions or call BS where I see it. I saw that at only a couple of stalls – the vast majority accepted their weaknesses (where they had them) and were mostly balanced. As a guide to the usefulness of having all these vendors in one place, there is a product I will be definitely looking at more closely as it offers something that I currently have to get from two separate vendors at twice the cost.
Technical seminars – the Monday session proved to be very informative. 4 x 2 hour sessions that maximised the useful information and minimised the fluff. It would have taken me days, if not weeks, to have accumulated that level of knowledge. For this seminar as with all the sessions I attended, to have the presentation materials to refer to whenever I choose means the fact I have a memory leak issue is seriously mitigated!
Breakout sessions – the wide variety of these was very impressive. They were also numbered so you could quickly determine the depth of knowledge being passed on i.e. 1### was for the introductory level sessions, 2### for intermediate, 3### as expected for the advanced levels. They ranged in length from 30 minutes to over a couple of hours. All of the presenters throughout the week were bang on the money both in terms of knowledge and presentation skills.
Lab sessions – these came in two flavours. Walk in labs and instructor led. With the former, you book your slot (or chance your luck and turn up), and you sit down and work your way through the chosen lab. There were several to choose from and I opted for the CCIE OSPF lab. The instructor led labs were a bit more formal, at set times with (in myIPv6 lab at least) three instructors to help with any questions. There was little instructor led learning for the group. You just worked your way through the lab and asked questions if you had any. I found this session to be extremely valuable. I have always found hands on labs the best way to learn and remember topics and four hours configuring IPv6 helped me understand a good deal about it.
Meeting Key Cisco staff – where else would you get the chance to speak to the CTO of Cisco Learning to get key advice on my study path and probe about, for example, what Cisco are doing to protect the CCIE programme? Or speak directly to the IOS product manager about the timelines for features and platform standardisation? Highly valuable discussions.
Meeting your peers – I met some great people last week. Friendly, knowledgeable, geeky, willing to share their experiences, willing to listen to mine. I use Twitter quite a lot but it has limitations. The lack of the face to face feedback, the 140 character limit that makes anything more than a passing comment a chore. Sure, there are loads of nice people on there who can help you, but there is no captive audience. Chances are that most of my followers are still asleep on the other side of the pond if I expect an answer before lunch. Facebook is dead to me. The web as a whole offers all the information I could hope for, but sitting down for lunch, or a pint…or a vindaloo perhaps and just talking about ‘stuff’ is so much more sociable and that suits my personality much more and it’s back to the feedback issue…its instantaneous.
Inspirational – all of the factors above, crammed in to a single week? It was a real eye opener for me and I came back, despite the very long days, feeling energised, driven to get my CCNP done and move on to bigger and better things, get a plan together for both IPv6 and more global WiFi rollouts within the company and to spread the word as to what is happening in the industry.
Perhaps this post will help you decide if you think Cisco Live is worth attending if you haven’t already. Do I think it was a worthwhile event? Surely you know the answer to that from this post alone, let alone the daily updates I posted (you have read them all haven’t you?!!). I’m already asking the question about if my company intends on sending people there next year.
Would I pay £4000 myself for such an event? If I had that kind of money to spend without it stinging, without a doubt. The fact is though that it would sting but let me make a final comparison to put things in perspective. Being a predominantly self-taught person, I’ve been on only a handful of courses in my IT career. These have usually come in at the £1000-£2000 mark, and that is just for the course i.e. only £0-£1000 cheaper than Cisco Live. If I take the extreme case and say would I pay £1000 more for Cisco Live than the best of those IT courses, then I would say there is no question. I absolutely would and I’ll be gutted if I don’t get to attend again next year, and the next, and the next…
I woke up this morning with mixed feelings. On the one hand, I was very excited to get back home to see Jo and Mia, my wife and daughter. Although this week at Cisco Live London 2012 has been a phenomenal experience, I find that I really start to miss them both after a few days away. The flip side of that excitement was the genuine sadness that the Cisco Live week is over. I am very fortunate to have been here, learnt some amazing things and met some quality people. Once the dust settles a bit, I’ll post a summary of the week and explain why somebody in my position found it to be so incredible.
OK, back to the task in hand – what happened on day 5. The last day is a half day and the World of Solutions section closed yesterday afternoon so I was keen to make the most of the morning and had booked in to two sessions. Funnily enough, these were the original two sessions that I had signed up for when I first got my online account. Pretty much every other session had been swapped about before I finally settled on them.
The first session was on OTV. Max Ardica did a great job of covering the topic considering the 90 minute time frame, although it is one of the more easy to understand concepts. OTV is effectively a Layer 2 extension feature, which used in conjunction with LISP, for example, has some real potential. This is a relatively new feature that is maturing at a steady rate. Overlay Transport Virtualisation creates a tunnel or multiple tunnels over a Layer 3 IP network and allows Layer 2 communication across it. Assuming you have the bandwidth for it, it means you can VMotion across geographical locations and using this in conjunction with LISP will allow your external access to find the services in the new location with minimal outage (when I say outage, I am talking about a single packet drop, so outage is not really the right word).
Despite the Cisco Live party last night and it being the last day both this and the last session of the week were full up, which surprised both presenters!
The last session was on the evolution of IOS. This turned out to be more interesting that it might at first sound! First of all, Cisco are committing to making the whole numbering and release fiasco more standardised across all platforms. On that note, there is a strong desire internally to standardise the CLI platforms themselves but it’s not going to happen in the next 18 months. What will happen before then is a more frequent release of SM (standard maintenance) versions with regular EM (extended maintenance) releases. This harks back to the good old days but since 12.4\12.2 on the routing and switching platforms, the numbering system seemed to be set to reach infinity and releases were not nearly as common as they used to be. The presenter (whose name was not on the slide and whose face doesn’t match the name on the Cisco Live website for the session) was the first to admit that there are still a lot more improvements to be made.
The subject of licencing of course reared its head and after reviewing customer feedback, the current model is being overhauled to a ‘Right to Use’ system, effectively based on trust. You use, you buy, but you can install an IOS for evaluation purposes and doing a ‘show licence’ will reveal which licences are under evaluation and which have effectively entered the ‘be honest’ phase.
The IOS is moving to a more modular system, where each feature is available in a release and you turn on what you need. In addition, there was talk of feature virtualisation so that, for example, a firewall feature would run in its own computing process separately from OSPF, so that if one caused issues, it would not crash the entire system. Playing in to the modular approach, a role based access method could mean that your firewall guys could log on and only see the firewall process CLI, your routing guys the related processes etc. Perhaps too much granularity for anyone other than the really large shops but I can think of a few good use cases at my current role.
Another feature coming down the line, which I thought was very cool and also long overdue, is the ability to have a Wireshark process running on a switch\router that could packet sniff without having to put a separate device inline. 1984 made easy, 28 years later.
As a late snippet of something I learned yesterday in one of my IPv6 sessions, OSPFv3 will be supporting IPv4, hopefully from next year. Its improved convergence alone makes this good news, but nobody will be running IPv4 by the end of 2013 anyway, right?
Well, I’m at the airport now with five hours to kill thanks to a cancelled flight and intend on catching up with a load of stuff, so…
As much as yesterday at Cisco Live London 2012 was about the WAN for me, today was all about IPv6. Well, beer and curry and IPv6 too. At the start of the week, today was going to be about learning more about UCS. Following on from the excellent seminar on Monday, and my colleague’s recommendation of the IPv6 intructor led lab (that he attended yesterday), I decided UCS should take the back seat so I turned up 15 minutes early to be first in the waiting line – this session had been fully booked. Thankfully, not everybody booked in turned up by 08:57, which is when they start letting the people on the waiting list in.
Bam!! Four hours of labbing, with three excellent instructors on hand to answer any questions. There were seven main labs, with four optional ones. I made sure that I fully understood everything I was doing before moving on to the next part and was glad to have made it through five of the seven main labs in the four hours. Missing the last two did not concern me as the lab is available for download and the topology will be easily created in GNS3. As I tweeted later in the day, I will be setting up IPv6 at my home in the coming days and seeing what IPv6 only resources I can access on the Internet. The best way to understand IPv6 is to get stuck in and see what it does. I could feel my trepidation fading away with each successful confirmation that I’d configured it correctly.
The afternoon brought two IPv6 breakout sessions, the first delivered by Cisco IT about how they implemented IPv6 in their own business presented by Khalid Jawaid, the second a session on planning, deploying and things to consider presented by the very capable Yenu Gobena. Although the Cisco IT session was good, the second one was far more informative for me and rounded off my IPv6 day nicely…
…just in time for Net Beers. Yep, last night of Cisco Live is party night but instead of heading straight to the main event, myself with @ghostinthenet and @ccie5851 (Jody Lemoine and Ron Fullar respectively) met up with @xanthein (Jon Still) who unfortunately hadn’t been able to make it to Cisco Live. A good night was had by all and it wasn’t long before Jody was outnerding us all with his knowledge of Sci-Fi & fantasy, history and many other things too. He also won the ‘Matt’s favourite T-shirt of the week’ competition:
At about 21:00, I was feeling rather peckish so Jody and I said our farewells to Jon and headed to the Cisco Live party. The setup was pretty cool, although most of the food had already been taken by that point so when Jody said he felt like a curry, I told him I knew a place! So off to Brick Lane in Shoreditch again for a chilli masala and a vindaloo for Jody (at a different place from Monday, not quite as nice but very pleasant). And so another post midnight day came to an end, I thought I’d keep today’s post a bit briefer.
Two sessions tomorrow to take me up to lunch time, then it’s back up north of the border. Will give an overview of those as soon as I get the chance and a summary of the week as a whole. Also, in light of today’s sessions, I’ve changed the tagline of the blog from “The 127.0.0.1 of networking”. It’s all about progress!!
Day 3 at Cisco Live London 2012 and yes, it’s true. I have whored myself today with no shame nor remorse, but more on that later. The day started off so well too!! Today, the primary theme for me was simply WAN. Optimisation, high availability, security and best design. Both sessions were delivered by Adam Groudan, a man who touts himself as Cisco’s WAN evangelist and it was soon clear why. It’s always nice to sit and listen to somebody who really knows their shit, especially when you yourself might not! If I was to give you two topics to go away and read up on, it would be DMVPN and Performance Routing (PfR). Am looking forward to trying this stuff out on the lab.Then came the first whoring of the day. A tweet I sent out on Monday:
Just put my hand to head and found brain tissue leaking out of ears. Thanks @CiscoLiveEurope! That was some technical seminar #CLEUR
This caught the attention of some of the guys in the social lounge and they asked if they could do a quick video interview on how I was finding the event and if they could use both the video and the tweet in their marketing material. Sure I said, as long as my Twitter handle is included! I have just started blogging after all and knowing that there might be more people reading it keeps the motivation going…..no…..please dont go!!
Following on from that, it was off for the 2nd and final keynote speech of the week, presented by Cisco Futurist Dave Evans with guest Richard Noble, the holder of the land speed record until 1997. Dave presented a very intriging 10 things to look out for in the next 10 years. I unfortunately had to bomb out at number 8 for a meeting with Cisco Scotland so will watch the keynote on Cisco Live Virtual. If you like tech and progress, I strongly suggest you do too…it was very interesting and Richard’s part juts showed what an amazing field engineering is. The Bloodhound car (picture posted in last blog at the end) is at the pinnacle of technological progress. The thing that really blew my mind was the fact that this car uses a Cosworth F1 engine….it’s job is to pump the fuel required for the jet engine!! An F1 engine required effectively as a pump for a bigger engine. If I recall correctly, that car throws out something like 70000bhp. I will be watching the television coverage when the new record attempt is made, hopefully next year.
Lunch today was provided at the Crown Plaza hotel courtesy of the Cisco Scotland team for attendees from a Scottish company. Hell, it was a free bit of tasty lunch so I didn’t want to tell them I am actually English in case they barred me. Of course, there is no such thing as a free lunch but the 30 minute marketing pitch on their UCS offerings was actually quite informative.
The afternoon brought the 2nd WAN session mentioned above and then I attended a useful 30 minute session on the value of certifcation and how it can help your career. This was presented by David Mallory, the CTO for Cisco Learning and we had a good 15 minute chat after the session on the value of different study methods and materials, how to approach the CCIE lab and what to expect and what Cisco are doing to keep the very high standard of their different tracks and levels of certifcation. Where else could you get that kind of high value information in such a condensed time?
And now, for some more whoring news. Before Dave Evans began his keynote speech this morning, Darren Cambell came on to take part in an Xbox 360 Kinnect competition with some of the attendees who had somehow managed to find the time to play a Cisco Live game. In the early afternoon, Darren was doing a meet and greet at the social lounge and with him being from Manchester too, I thought I’d go and have a chat. Now, for those that dont know me, I’m not shy in the slightest so charged up to him and asked for a photo opportunity which he willingly supplied. Please note the Gold medal around my neck that he picked up at Athens 2004 for the 4x100m relay. He’s only 3 months younger than me but still looks like he’s in his 20’s. Makes you sick really! Joking aside, he’s a really nice bloke.
Another whoring alert just in, I recently tweeted Jimmy Ray Purser of Cisco fame asking for a photo to which he replied in the affirmative. So when I turned a corner in the World of Solutions and saw both him and Robb Boyd having their photos taken, I introduced myself and asked him to uphold his end of the bargain, despite me offering him nothing in return! They were in the middle of a photo shoot themselves but dropped everything straight away and Jimmy had a good chat with me about things in a completely relaxed way before I stopped annoying them any further.
The final ‘this whoring news just in’ was when, at the morning’s WAN session, Adam had about 10 little boxes of magnetic Visio style network icons to hand out to people who asked the best question. Of course, as soon as he said that hands were popping up all over the place. When my question, which deserved a box for being the most retarded of the week, didnt get such recognition, I ended up approaching him at the end of the session, noticed a spare box on his desk and told him that I was trying to get my daughter in to network design and that the box would allow her to do this over her cornflakes in the morning. Box…in the bag. Thanks Adam. She is only four at the moment, I should add, but I’ll be showing her, using the icons, how one might design a redundant WAN solution!
OK, I am seriously goosed but they are handing out free beer so I’m off for the night. Planning on being sensible…ish tonight so I can give it my all for the last full day, then on Friday, its off to the Cisco store for some much coveted books.
Day 2 at Cisco Live London 2012 began with the immediate realisation that lots of attendees didn’t come to yesterday’s technical seminars. It was absolutely heaving with wall to wall nerds and geeks with the dweebs sitting in the corner.
The first session of the day was the week’s first keynote speech, given by the CTO of Cisco Padmasree Warrior. There was a big show with performers waving some light wand things about that generated different flags of the world on them and lots of loud music before an introduction by some bloke that I should probably know. Whilst Padmasree’s talk wasn’t anything revelational (by that I mean it was pretty much all known or expected), it was good to hear a fairly complete set of Cisco’s strategies reeled off in an hour session. There was a technical demonstration on the rather expensive looking kit below:
Apologies for the low quality pic but the lighting was being all funky. It is basically a UCS system sitting on top of an EMC VNX storage device with 6500 Catalyst switches and some ‘lower quality’ non-Cisco switches. It was a video conferencing demo but the cheese factor was turned up to 10 when the distinction was made between the Cisco super duper switches and the meh ones by showing a jittery video call being placed, the ethernet cable being taken out of the crap switch and in to a 3750 when the video was just perfect. I wonder how many other techie guys in the audience were like me and just wanted to console on to the crappy switch and check the config out!!
Another demonstration was carried out that was more impressive. The photo below doesn’t really do it justice but it was a video suite that acts like a greenscreen (but without being green, a more business like grey was acceptable) and allows you to put in an active backdrop e.g. perhaps a studio with a TV screen with active content such as a video or presentation). They then ‘teleported’ one of the female UK 5K atheletes on to the screen next to them from another video suite so they appeared side by side. I say you cant beat just picking up the bloody phone but I was impressed by the technology nonetheless. The ‘real people’ can be seen on the far right, missing the athelete who appears on the screen.
After the keynote speech, I then had a couple of hours to browse around the various vendor stalls as I had cancelled a session late last night on an introduction to UCS which I felt was a duplicate of what I had learned in yesterday’s technical seminar. I will cover the entire ‘World of Solutions’ floor this week but today, there were two stalls that I thought I would talk to you about, and unfortunately do not have any photos so you will need to go to their websites for more information.
The first was a company called SevOne, (www.sevone.com) who provide a network performance management tool in the form of pretty much an all in one appliance, each model sized for a certain number of objects (ports\interfaces etc.). You pick the polling period and the first 30 days of data are stored (along with the bastardised Gentoo distro OS) on fast SSD drives. Data from 30 days to 12 months are stored on normal spinning disks but the key difference from, say Solarwinds Orion, which I am more familiar with, is the device does not roll up any of the data, so in 10 months time, you can view the data as it was polled, not a hourly summary for example. Another good selling point was that buying the device buys you a high level of support too so if you need to update the software, they will do it remotely for you, they will help keep your database healthy etc. Finally, the fact that it has Netflow capabilities built in meant that you can use it out of the box. A nice touch to the one on one demo I got was a zoom in on a particular network spike, a button click brought up the Netflow data and the culprit flow was visible immediately. Quite a nice all in one solution from my first glance.
The second stall that I was impressed by were selling smartboards. I believe they may have been called Smartboard but my memory is failing me! The simplicity at which these things operate was what first occured to me. They were very intuitive and the guys hosting the booth knew it as they stood back and just let people play about with them. The collaboration possibilities stood out a mile as you can link multiple smartboards across physical locations for a true brain storming session. There is an iPad app that would allow users of those devices to consume the content as well as add to it. The devices are Powerpoint aware meaning you can open a presentation, add scribbles and notes etc and save the presentation in it’s amended state.
It was actually at this stall when the nice Canadian chap (another attendee) I had been speaking to looked at my name badge, then at his phone and said “are you Vegaskid?”. It turned out it was @ghostinthenet, Jody Lemoine. It seemed slightly surreal to me to have been ousted in such a manner, especially as I had replied to a tweet of his not more than an hour earlier. It’s always nice to put a face to a name and we had lunch and a good chat. There was mention of net beers which I believe is a tradition at such events so looking forward to a couple of those!
I won’t dwell on these points too much but a couple of disappointments today were the WiFi and the fact that one of my sessions on fast routing convergence was over subscribed. The WiFi issue ran on all day but the event organisers are reporting that it should all be fixed for tomorrow so fingers crossed. The over subscription issue was a little annoying, but thankfully it wasnt on my ‘must go to’ session list so I didnt let it annoy me too much.
Later on, I also bumped in to Ron Fuller (@ccie5851) at the Nexus stand and introduced myself. It’s quite interesting how keen and good network engineers can be at the other kind of networking. We are quite the social animal!
I had a two hour session in the afternoon based on enterprise WLANs, which whilst not deep dive enough for me, considering my recently acquired project to implement a two controller, eight AP solution, it gave me enough to get on with it with a little more confidence. Below is a picture of the presenter who was very comfortable with his subject matter.
That took me to 17:45, when the drinkypoos started. So what did I do? I grabbed a beer and a glass of wine and headed over to the walk in labs and decided to take on the CCIE OSPF lab. Not for the first time today, I found myself in a surreal situation with people getting merry all around me and these guys playing music just outside the lab area. Whilst good fun, I did find their musical talents a little stilted….oh dear, back to the day job Matt!
I realised about two questions from the end of my lab that I hadnt rang my wife and daughter to see how they were so did so before my iPhone battery gave up the ghost. Having got about 75% of the way through the topic of OSPF for my ROUTE exam, I found the CCIE lab at quite a good level to keep me on my toes. I think I’ll maybe pop in for another one before the week is out.
Finally, the car attempting to break the world land speed record (at 1000mph apparently) was on display. Wouldn’t want to reverse park it!
OK, it’s now already Wednesday and I am goosed so that’s it for now.
First of all, WOW. The vibe at Cisco Live London 2012 is quite amazing. A two minute walk from the Princes Regent DLR stop takes you in to the Excel exhibition centre and the registration process was over in another two minutes and the first souvenir of the week, the obligatory CL backpack, was in hand.
The technical seminar I had signed up for was the ‘catchy’ sounding ‘TECVIR-2002 Enabling the Cloud: Data Center Virtualization – Applications, Compute, Networking and Best Practices’.
The three presenters over the day, which stretched to nine hours, were Carlos Pereira, Santiago Freitas and Ray O’Hanlon. Each had their own style but all were very capable speakers\presenters which kept me engaged for the individual parts which ran up to two hours each. Carlos in particular was a natural and the demonstrations given by Santiago were nothing short of breathtaking.
I did think if nine hours was enough to cover the broad range of topics in any real depth but these guys have done this before and the fluff was kept to a minimum, at least for the first half of the day. Any attempt for me to judge the quality in the afternoon would be futile as I was just trying to understand as much as I could, despite the fact I have the slides to refer back to.
Fabricpath, UCS, OTV, LISP, FCoE, VXLAN all got good representation and of course how they relate to ‘the cloud’. I am thoroughly relieved to know that my idea of what cloud is matched fairly well to Cisco’s. Note that this post is a general overview of the day. If you want to learn about the specifcs of these technologies, there are already plenty of online resources which do a better job than I could at this stage…my head is still, at 22:30 filing whatever it can remember away. Where it was evident that the topics could have been turned up further on the nerd meter to 12, references were made to the specific technical sessions later in the week with a suggestion to attend. Despite having swapped my schedule about several times in the preceding weeks, I think tonight will see yet another juggle!
What I liked today was that nobody’s knowledge level was taken for granted. The presenters were very good at sensing the tone when something being discussed needed more depth…probably the furrowed brows around the room. It was also amusing that some people were using today as a ‘how do I fix this issue in my production network’ session.
Firstly, I still struggle to see what questions a lot of the new technologies are trying to answer. For example, take OTV, please (OK, old joke). After discussing the innards of this technology, a quick poll around the room to count the number of people who were extending their layer 2 domain across physical sites caused one slightly shaky hand to raise. And it seemed that nobody was going to return to the office next week to implement it.
Secondly, as Bob Dylan said, the times are a changin’. Networking is undergoing a huge metamorphosis, unlike anything I’ve seen in my years in IT. Love it or loath it, cloud is here to stay and it’s going to take a whole new skillset just to understand it, let alone plan, design, implement and operate. The current standard of logging on to 50 TOR switches to configure individually could very well be coming to an end as the control plane is centralised. Add a super smart management platform on top and productivity has the potential to go through the roof. That’s once the questions are properly defined and the right answers agreed upon. That’s not even talking about the questions that are only relevant to you.
Finally, Cisco Intelligent Automation for Cloud (CIAC) looks like it has the potential to put a few people out of work, to say the least. The demonstration of LISP and OTV working together was very impressive, with a VMotion between data centres causing only a single ping packet to drop but what really stood out for me was the self-service portal demonstration which showed a brand new ESX host being deployed as production ready in less than 30 minutes with just a few clicks. In addition, a VM was deployed to another host with correct network settings (both at the VM and network ‘pod’ level) and security settings applied. It looked like a lot of work to set up, but a dream to run.
I’m goosed and have another 3.5 days to get through. Luckily, the rest of the week’s sessions are shorter. Here’s to learning new things.
Cisco Live London 2012 starts next week and myself and a colleague of mine have been fortunate enough to be sent there at the expense of our company. There have already been the odd ‘oh, off on a jolly’ comments from some workmates but jealousy and joking aside, next week will be as far from being a jolly as I could imagine.
My schedule can testify to that alone. I have also been allowed to go to a technical seminar on the Monday which runs for 9 hours. Each day thereafter is crammed full of keynote speeches and breakout sessions and the small gaps inbetween will be used to shoehorn as many stall visits as possible to see what is out there. Add in a couple of evening networking events and I imagine I’ll be sleeping for a week afterwards.
I am also hoping to get some blog posts up about my experience so watch this space. Till the next time…
Just before the end of January hits us, I thought it would be a good idea to put my 2012 study wish list down in writing in the form of New Year’s resolutions. This will not only be a valuable checklist for me, but will provide motivation as the year moves on and putting it on my website will drive me on further.
I want to do the numbered items in that order. I’m being sensible this year as I want to make sure my CCNP reflects a good knowledge and not just good exam skills, especially with me only moving over to networking officially last year.
2013 should be even more exciting, but I’ll not be setting those goals in stone until nearer the time. I already have a good idea of what I want to do next year but I’ll be more focused if I keep that open and get my head down for the list below.
CCNP ROUTE – having already passed the SWITCH exam at the tail end of 2011, I’ve already started studying for the ROUTE exam and have just about got EIGRP and OSPF out of the way. I’m hoping an IPv6 class I’m taking at Cisco Live London next week will help me in that area and that leaves BGP and route redistribution for when I return. However, I’m not in any rush and have a date for the exam of May time pencilled in
CCNP TSHOOT – I want to give myself three months from passing ROUTE to have a go at this exam. Again, that’s plenty of time but I really want to make sure my CCNP is solid. After all, it’s just another step on the journey…one that never ends
CCDA – no set time for this one other than just wanting it by the end of the year. I think design skills are critical for any IT engineer, but in particular in the field of networking. As well as giving you an understanding of why the pieces of the puzzle do, or perhaps do not work together when troubleshooting existing networks, it is a skill required of network architects
CCNA specialism – not sure which one. I like the idea of doing the Wireless and I love the whole topic of IT security. Either way, I intend on getting both of them, but only have my sights set on one for 2012. With a new wireless deployment coming up at one of our offices, I think I may let that sway my decision for now
I brushed over this on my initial post but I am going to flesh it out here, primarily to keep me motivated on the way.
Decision made and I’m 100% committed to the networking track so enough of the Microsoft certifications. I may very well upgrade my server certs when the next version comes out but that doesn’t appeal to me at the moment. I am set on becoming as good a network engineer in a way that is focused and in depth and use that as a strong foundation to build upon. Microsoft has given me a great career to date working for a number of wide and varied companies but when I passed my CCNA back in February 2009, I knew I was hooked.
I first wrote this post with a list of all the certs I have in mind for the next 1-5 years but it ended up sounding like a exam junkie’s wet dream, when my goal is knowledge, not just a certificate. Personally, I find the latter a useful measure of the former but I’ve worked with many people in IT who thought that the paper certificate was worth more than the knowledge required to get it and understand it. I refuse to be that person and want to be proud of my skills, with certificates that reflect that as an added bonus. There have been some great blog posts recently in the networking community around the value of certification and I may write one myself in the future to give my thoughts in more depth.
So, what methods do I use for training then? For each exam, where feasible and relevant, I approach training as below:
Books – either the specific exam guide book or one that covers the main topics. Cisco Press books have come a long way since I first started reading them, although they still need to tighten up their proofreading, but having the topics laid out in a logical order is very useful. I find using books on the networking track much more useful than when I studied for Microsoft, where videos and hands on worked more for me
Video training – either CBTNuggets, but recently my preference is for INE. I am lucky that my company pays for subscriptions to both and also all my other training materials e.g. books, exams
As I go through the various video topics, I fill in the gaps and supplement my knowledge with books and the web. I am trying to get myself more acquainted in particular with Cisco’s Doc CD site, which is a must for CCIE lab candidates
Labs – with all the topics in my head, I head on to my INE based lab. This is part physical, part virtual and I will cover this in a later posting. As I am going through the video training, I often fire up GNS3 or, to a lesser extent, Packet Tracer on my laptop to walk along with the trainer and see similar output. I find this helps me remember commands when I come to doing the labs ‘proper’
Of course, to supplement all of this training, I am a network engineer by day (and sometimes by night!) and live environments provide some great challenges and help broaden my overall knowledge. I use the above methods for all my IT training with even more emphasis on the labs for the Cisco stuff, but outside of the ‘official’ studying, there is still the day to day knowledge to keep up to date.
I am on Twitter as vegaskid1973 (hoping to get this changed to lose the numbers!) and follow a number of high quality networking feeds. Come and follow me, but be aware its a mixed bag you’ll get from me! I also read different blogs and websites to try and keep my working knowledge up to date as much as time can permit. In general, I find that it all sinks in if I focus on a particular topic e.g. STP, OSPF, BGP and cover the videos, blogs, books, labs before moving on to the next topic,rather than going through an entire book, then video series, then labs, etc. Prior to doing the exam, its the hours of labs that I find most useful.
The last point I should make is based on work\life balance. Although networking for me is a hobby as much as being work (and I know how fortunate I am to be in that position), the time comes to put the books\laptop down and spend time with my wife and daughter who both keep me on my toes. I’m not sure if either of them know how much time I will need to put in to this but its all made easier by the fact I enjoy it so much. What is important is that you don’t let that side of things suffer.
I’ll post a quickie on my home lab setup and then I should be ready for some proper blogging! Till the next time.
Welcome and thanks for at least coming this far! I’ve considered running a blog since the word was invented. I’ve had numerous sites over the years but they all went through a dozen changes and not one involved interesting content to be perfectly honest. I’ve been holding off on getting the ball rolling but with my first visit to Cisco Live coming up in a few weeks, thought that now is as good a time as any.
Initially I looked at Blogspot, liked the look of a couple of blogs and thought I’d write a small number of hopefully useful posts, outlining my rise in the world of the network engineer, in particular working with Cisco kit. But two posts in, I thought to myself, why not get the domain name I’ve always wanted and host the blog there instead, which is where we are today.
To give a bit of background as to who I am and where I’ve been, I’ve worked in IT full time since 2002 as a Microsoft engineer, attaining an MCSE 2003:Security, MCITP:Server and Enterprise Administrator and specialising in Exchange 2007\2010 in that time. In 2008, I started studying for the CCNA certification to broaden my horizons and six months later, having taken the ICND1\ICND2 path, was the proud owner of a CCENT and CCNA. I carried on specialising in Microsoft technologies, in particular Exchange and put my CCNA skills to use with basic configuration\troubleshooting on our internal network and on some of our customer’s infrastructures.
A few months ago, I was aware that my CCNA was going to expire (Feb 2012) and it was at that point that I was in the fortunate position of suggesting to my line manager a move to being a full time network engineer, which both he and the company supported…result! Within six weeks, I’d resat my CCNA as I wanted to reaffirm my foundational skills before moving on to the next step, the CCNP. I’m originally from Manchester but with family ties in Scotland. For the last four years I’ve worked for an ISP\hosting company in the North East. The initial aim of this blog was to document my journey through the valley of Cisco certification, but I soon realised that I would be restricting my content. So in short, this will be a technology blog with a heavy emphasis on networking.
Although my plans may change in terms of the order of things, I intend on gaining my CCNP in the next 9 months (have already passed my SWITCH exam), spending the following 12-18 months looking to gain some design certs (CCDA\CCDP), perhaps CCNA Security or Wireless or perhaps even a currently job relevant CCIP. No more than three years from now, I hope to be in a ‘comfortable’ position to take on the CCIE R&S written exam and lab.
If somebody ends up finding it useful, then all the better. In fact, if somebody ends up finding it at all, I’ll be happy. As a final note, please feel free to contact me at (vegaskid at vegaskid dot net) if you have any suggestions or questions and do make yourself at home. Till the next time…
