Hiho.

I'm by no means a complete noob when it comes to networking but I've never really had to deal with managing a large network before, nor have I ever used any kind of SNMP.

Does anyone have any links for good starting points for me to read up on? The network will consist of ~400 clients connected to various desktop cisco switches, gig (or 2x1gig depending) uplinked to a 54port gig layer 3 core switch. , for all the difference that makes. The network will be seperated into VLANs and all that malarky.

I'm going to have a route around on google myself but I just wondered if any of the more grizzled vets in here might be able to help out :)
 
Something we've been trying to look at as well in implementing SNMP monitoring of our network and other devices as its something we don't do at the moment.

From what I can tell is that its a standardised system so you just need the server to receive the traps and alerts. I've had a look at Microsoft Operations Manager as it seems to have management packs for everything we need, but this might be overkill for just looking at snmp.
 
Its a big area and some of the things you might be interested in doing are:

Patch Management
Security and Event Log consolidation and Monitoring
Host Status and Error Trapping
Service Status and Error Trapping
and much, much more....

I work on a very large network that is using some tools from CA to achieve all of this and its not bad (the parts I'm responsible for are well catered for).

However, I'm also responsible for a totally seperate 100 node network and I deployed Nagios to make my life a little simpler.

http://www.nagios.org/

Its free and open source, well supported with plugins and can be experimented with very easily (pre configured VMware virtual machines are available).

Its quite nice but nowhere near OpenView, BMC etc for obvious reasons.

I didn't have the budget for anythign special so I just chucked this on a VM one day and had a play around monitoring some simple services and hosts at first and built it up from there.

Great piece of monitoring software, very good for capacity management, not sure on a plugin that will handle SNMP traps, but has a load of other good plugins, for things like network maps etc...

No issues with Casti here either - just found Nagios the easier one for me to get setup (they have a preconfigured VM to play with and I'm a VMnut).
