LMS 3.2 (CM 5.2.0) User Tracking ability lost after switch to SNMP V3

BKDAFBCCO · ‎05-04-2010

After converting from SNMP V2 to V3, User Tracking (UT) no longer collects end hosts from c3750s. Have tried adding multiple "view" starting points to no avail... Anyone using SNMP V3 and able to track end hosts on c3750s?

thanks,

In order for SNMPv3 to work, you need to configure SNMP Context access for all VLANS. You need to allow the current SNMP group access to those VLAN contexts with commands like:

snmp-server group GroupName v3 context vlan-1

This needs to be done for every VLAN that User Tracking will need to poll. Use the command "show snmp context" to get a list of all contexts on the device. Then configure them as seen above.
