Problem to access the CAM table via SNMPv3

Hi folks,

I have a problem to access the CAM table of a Cat2950, IOS 12.1(11)EA that has been configured to work with SNMPv3 auth only. I tried to use the net-snmp toolkit to access the bridge table w/o success. The switch config is:

snmp-server engineID local xxxx

snmp-server group test v3 auth read readView

snmp-server view readView mib-2 included

snmp-server community public RO

snmp-server user bob test v3 auth md5 bob1

And the command I'm using to fetch the table is:

snmpwalk -v 3 -a MD5 -A bob1 -u bob -l authNoPriv <device IP> .1.3.6.1.2.1.17.4.3.1.2.<Vlan ID>

I'm just able to get the vlan1 mac addresses. I cannot access other vlans as it says "unkown username".

Thanks,

Yigal

Looks like you are running into CSCed07927:

This BRIDGE-MIB doesnot support VLAN contexts for SNMPv3 on IOS

The defect is resolved, but yet to be integrated into an IOS that is publicly avilable.

Thanks for the prompt answer. However I cannot find this bug ID via the Bug toolkit. Does this bug covers

all the IOS-based switches with the current releases?

Thanks,

Yigal
