I'm looking for some input from anyone using NAV with Cisco 3750 switch stacks. If you have a stack of 2 or more 3750's and all the L2/L3 interfaces are being properly pulled from it by NAV, then would you mind sharing what version of IOS you are using?
I think I may be running into an SNMP issue with the particular version of IOS I'm on. I get timeouts when querying the 3750 via SNMP. I can do an snmpwalk from the NAV server to the device, and it runs for a while, but it will sometimes time out.
