Look what ive just won for 80quid on ebay
http://www.ebay.co.uk/itm/Cisco-Catalyst-6509-Ethernet-6248-Fibre-6408-E1-6608-/290607240135?_trksid=p5197.m7&_trkparms=algo%3DLVI%26itu%3DUCI%26otn%3D2%26po%3D LVI%26ps%3D63%26clkid%3D2818959360003296866&autorefresh=true#ht_2617wt_18146
Will go nicely on my network map (http://ants-network.co.uk) :)

My first comment would be "Geek" But that's only because I am jealous of the setup...

Im currently working on my CCNP so this will be a good investment for the future for studying
80quid though, I paid 120quid for my 3550 and 380 for my 2811

Was going to ask why, but that explains it :mrgreen:

Wow building hardware labs - you kids still doing that?
After all, whats wrong with this (http://gns3.net) and having a nice simple network at home?

Im not a kid im almost 26
Many people i know build labs or virtual labs however in my opinion its not that great of an idea, i prefer to run the network "live", if the internet goes of my mrs moans so it makes me fix it sharpish

Oh believe me, I have been there, done that, had the certification, left the full-height 19" rack and some kit in the garage when I moved because I just couldn't be bothered moving it with me.
However if I could go back again and just do it all in a virtual environment, instead of on a bunch of surplus to requirements 2500's and Cat switches, sitting in a rack taking up space, slurping down electricity, then virtual would win EVERY time.
Well surely you want to simplify the network? If all you have to worry about is the ADSL/Cable router you can just tell her to switch it on and off again herself.
Not bad, the noise will start to bug you about 4mins after you plug it in though!

I enjoy messing around with real kit, for the sake of 80quid i will gladly put that in my home network. Call me a nerd if you like :)
I remember the days when i first started at uni, you would get guys passing a ccna/degree who have never even touched a real device they just used packet tracer or gns
Going back 5 years ago
One guy set up a network with the usual nat, acls etc and put a webserver external and was chuffed that he could browse to the webserver via IP, he was a bit upset when i told him DNS wouldn't work so in a real life situation the internet wouldn't work.
I know loads of people at work who do play around with virtual labs all in esxi, checkpoint firewalls etc however i wanted to play with checkpoint firewalls so i just put one in at home, it gives a real idea of impacts. Example I found that checkpoint r75 with application control loaded on absolutely battered the FW when a new policy was pushed which made any connection through the FW run like crap - if I had run that in a non live lab how would I of known?
I understand where your coming from though
You will also need a c19 power cable to plug it in!

As do I with you - as said I was about the same age as you when I was as keen as you.
now my time is too valuable to spend hours getting 5% performance increase over a plug and play solution, you must have some pretty dodgy porn you are hiding from the Mrs if you are using VLANS at home :p
Oh and a friend of mine who is an Access Network Architect for C&W advises you look at Junosphere...
Junosphere... Is that as good as NSM? ;)

I work the odd night shift at work so i usually find time play around remotely,
No doubt when Im older i wont find the time and ill look back and think why did i bother.
The idea of the VLAN's is to protect again virus mainly, everything I download thats "dodgy" gets downloaded into the DMZ. Anything on that VLAN is the unable to initiate a connection to the internal network, oh did i mention im also a geek:)
I was going to wait for work to write of a extreme black diamond 6808, i don't need to bother now

I worked a lot of night-shifts, I used the time to learn Linux, Apache, Mysql and Php - first project I worked on for myself was a network discovery tool that created a network map usind SNMP, this was before Cisco etc did such a thing (or at least an affordable thing)

Networks, how very last century. Every man and his dog now thinks they can set them up and manage them. We now leave it to the kids, after all we did the hard work 20 years ago.

I depends what you mean,
We had a council (who shall remained un-named) who until 2 years ago had vlans extended out to over 150 sites with the l3 boundary sitting on a pair of core switches, that was an easy network installed 15 years ago
The hard/time consuming part came was pushing the l3 boundaries out to the edge sites
I put this thread up to show what I had purchased, not for people like you to start ranting about how good you are and how im a stupid kid

You'll learn that too, that what you INTEND a thread to be very seldom works out to be what it actually becomes. :)

Its crazy, i post something yet someone feels the need to jump in and just spread misery. Why cant people just be happy? I see threads all he time with no interest to myself but i just don't bother to read them.

You posted looking for comments on your purchase.
I am pretty sure that any "Networking Geeks" who were doing the job when that box was first released (12 years ago) reacted the same way - with a great big LOL.
Again speaking for the others, we all did what you did, all were that keen, have all had it beaten out of us as work rarely allows you to do the exciting, cool stuff you read about in the Operating System manual, or explore the more exciting paths and configurations, so you get bored, the shine wears off and you wonder why your spare room looks like a store-room for the Science Museum.
Frankly you bought a clunker of an impractical (for the home) machine, that will turn your electricity meter into a cooling fan as it drinks the juice, will be noisy as hell. Its not like I haven't done the same, even in the near past - Ask Sudoxe about how hard I tried to punt a rather large and noisy Sun Server at him (hint I only powered it up once and after that it became a coffee table until I found someone that actually had a use for it, and that was in the last couple of years.
Chill, you are experiencing the ribbing that the more experienced give out to the less experienced, partly its jealousy (not at the kit, but the levels of "give an ar*e" that you still have.

Not having a go.
When I was setting up networks, we were at the limits of the then available technology and infrastructure. What we wanted didn't exist.
For instance I was tasked with establishing data/voice to a site in China. It ended in one of our guys sitting in the ministry of post and telecomunications in Beijing to get us permission to establish the first privately owned satellite earth station in China. Now you would simply phone your local telecoms co and ask for an X25, or IP over a carriers MPLS infrastucture etc.
When I first got into networking I was writing device drivers for simple file sharing over a star lan over RF connections that pre dated CSMA/CD etc. We knew what we wanted to do, but the technology wasn't there. That is what I mean by the hard work.
Today, you have an interconnected world. It is expected devices will talk to each other, it used to be difficult to get two different suppliers VPN equipment to communicate as all would have subtle differences in their implementation of standards.

I don't know what your layout is like, but my garage gets hot enough in the summer to trip the temperature alarm on most kit. The stuff that doesn't trip becomes seriously noisy as the fans speed up to max rpm.
On the plus side, your garage will be frost free over the winter.

I get what your saying, I know I have purchased a device which is practically stupid to run at home but hey im young, no doubt in 20 years ill look back and think WTF was i thinking.
To be fair I didn't win it on purpose, I just got lucky no one else bid on it. I put a low maximum bid in and expected to be outbid straight away

What is it, and what does it do?
:-)
A couple of years ago I decided to get rid of my last (there were more...) monster Compaq server from my loft 'data center'. I looked around on ebay and decided I couldnt be ar$ed selling just to get a fiver if I was lucky.
I dropped it on the skip we had at the time as we were renovating. Each time the skip guy turned up he would take the server off the top and take the skip away. Took me ages to get rid of that bloody thing. Since then VMWare has saved me many decibels and kWh. Embrace virtualisation, it'll save you a packet and you'll learn just as much.

I do use virutlisation for servers,
Using virtual servers is completely different from a network emulator

yeah, I know that. The concept of virtualisation is exactly the same though.

They are complexity different concepts
ESX/I or vmware can perform a function and interface as a real server, so your laptop can connect to a virtualised file server or domain controller.
GNS3 is an emulator not a virtualised router or switch, so in no way what so ever can it act as a device on a network. its simply kind of "computer game" where the user emulates a network

I'm sorry but you are wrong and totally missing my point. I was not comparing technologies like for like, more that the virtual environment can provide you with all of the realism necessary to learn many of the same skills. I'm no beginner either, I've been in this field alot longer than I care to mention.
With server infrastructure we saw exactly the same level of scepticism with regard to virtualisation. Eventually we saw the light and emptied our home labs of unnecessary hardware.
