SNMP Bridge table in Cisco Catalyst 4006

Hi,

I'm trying to access sevaral Cisco 4006 switch bridge table using SNMP OID: iso(1).org(3).dod(6).internet(1).mgmt(2).mib-2(1).dot1dBridge(17).dot1dTp(4).dot1dTpFdbTable(3).dot1dTpFdbEntry(1)

Unfortunately, I always get ports as 0. I checked the access permissions for the community name I used, and it seems OK. Any idea whether this particular switch doesn't supports bridge tables?

Thanks,

--Ilan

Re: SNMP Bridge table in Cisco Catalyst 4006

After investigating further, it appears that this particular OID doesn't returns persistent data. Sometimes we get only MAC addresses without port indexes; sometimes only port indexes; some times only port indexes, but different from the ones we got a few seconds ago; etc.

ANY IDEAS ???!!!!

P.S: The rest of the MIB works fine, different browsers and different switches (all 4006) gave the same, unpersistent results!

I think the issue is that switches running IOS have only limited support for the BRIDGE-MIB. It appears that the Mib is applicable only to the default VLAN.
