LAN audit
I am regular asked to perform LAN audits
What do you perform on a LAN audit ?
Mainly i check firmware versions
Location of racks and physical installation + patching => the spaghetti-ness of the rack
Get backup of configs
Check the topology of the network
Have a look at the possibilities for login, if the hardware is protected with a password other then default

Re: LAN audit
Identify all the hardware with firmware versions
figure out the physical topology and identify all inter-switch links
get utilisation stats for all these links (I use solarwinds)
rough survey of how many active ports there are
survey of VLANs and where they are extended to
survey of spanning-tree - configured? priorities set correctly?
survey of inter-VLAN routing, other routing static/dynamic
note any redundancy that's built-in
check all logs for recurring errors or interesting information
what monitoring is being done
where are the logs collected
security: logins using radius/AD?, telnet & http disabled?, DHCP-snooping?, loopprotect/edge-port/BPDU Protect on edge ports?, no untagged VLAN on any links?

Re: LAN audit
thx vince
I see us using Solarwinds for monitoring, why not use HP's IMC ?
Do you have more visibility with the Solarwinds tools or just own choice

Re: LAN audit
Well, because I have Solarwinds Network Performance Monitor on my laptop, so the first thing I do is log onto the network switches, use LLDP neighbour to identify the true topology (as opposed to the diagram they've given me) then I fire up Solarwinds, feed in all the node IP addresses, and within 30 minutes I can see what their network is doing - performance and errors.
I have no idea if you can use IMC in this way, unless you are assuming your customer is going to have it already installed, which would be great for you in doing the audit, I guess.
I guess the way I see it - IMC is great for managing an HP network (mandatory, even), but auditing one is a different issue.
