Ok, I have aboout 50 switches and SNMP works on all of them great. I have one layer 3 switch that has SNMP enabled with the same commands, everything is the same, but when I try to run some things that use SNMP the layer 3 does not work. Below is my configurations on all of the switches. The Layer 2's range in models but the Layer 3 is a Cisco 3550. Could someone please let me know why the layer 3 will not work correctly with SNMP?
I don't know whether this is the case here because I don't understand your problem fully. (And I hope you will elucidate it further.)
But this reminds me that sometimes you have to encode the instance into the community string when you interrogate it.
For example, if you want to interrogate the transparent bridge MIB of VLAN 1, you just use the configured community-string, for example CISCO. To interrogate the transparent bridge MIB for VLAN 100, you have to use community string CISCO@100.
I wonder if that is relevant in other cases, e.g. layer-3 VLAN interfaces or VLAN ARP caches?
