SNMP authentication failure for User Tracking

[adam.caggiano]

Hi,

In reference to this thread from a few years back, I have a similar issue on LMS3.2.1 (CM 5.2.2) ...

https://supportforums.cisco.com/message/641479#641479

I have hourly spikes in CPU on a lot of devices that I think is related to this. Packet sniffing shows the proper SNMP community string, but I'm getting auth fails. I took a look at the ANIServer.properties but can't make any sense of what I should be changing.

Looking up the MIBs doesn't seem to get me anywhere.

Any suggestions (J. Clarke--you know your stuff! or anyone from Cisco?)

Thanks

You'll want to set

UTGetSuspendedVlans=0

UTGetVlansOnDownPorts=0

in ANIServer.properties.

When you poll a switch for its MAC table using the BRIDGE-MIB, the community string that is used is in the format of @. The above prevents Campus from polling for vlans that are suspended or which do not have any active ports on them.

Also, if you are using SNMP v3, then you need to configure vlan contexts for the valid vlans on the device for the same reason.
