SNMPV3 issues

I am having trouble with snmpv3 being on our switches.

User data is not being placed on the port information tables.

I did a test with a V2 RW string and repolled and the user information came in with no issues.

What lies within V3 that is preventing user information to be populated?

You will need to add the VLAN context to the view group on the device for each VLAN.


eg.  Snmp-server group <groupName> v3 <auth|noauth> context vlan-<VLAN-ID>

Where the SNMP user belongs to <groupName>


So to add VLAN 16 & 17 do the following:

Snmp-server group MyGroup v3 auth context vlan-16

Snmp-server group MyGroup v3 auth context vlan-17

Thank you I will try this out and let you know.

Also by default is Vlan 1 allowed through SNMPv3 or will I have to create a context for this as well.

Will the switch automatically poll each context or how do I define this if multiple vlans exist? As the switch only allows one snmpv3 to be selected?
