Question:

Why do I get the error message "Bridge MIB is Unsupported" on a Cisco Catalyst?

Resolution:

The Catalyst switch includes one instance of the standard BRIDGE-MIB for each Virtual LAN in the switch. If the read-only community string is "public" and the read-write community string is "private", one would use "public@25" to read the BRIDGE-MIB for VLAN 25 and use "private@33" to read and write the BRIDGE-MIB for VLAN 33.

If just "public" or "private" is used, the BRIDGE-MIB for VLAN 1 is accessed.
