[tkined] dot1dTpFdbAddress and Cisco 2900

I am using Scotty to walk through a Cisco 2900XL dot1dToFdbAddress
table in order to find a MAC address on a port after a "link up" trap
is received.

The switch is connected via a 802.1q VLAN trunk with multiple VLAN's

My problem is this: When the vlan of the port sending the "LINK UP"
trap is the default (Vlan 1), the MAC address nicely appears in the
dot1dTpFdbAddress table as expected.

If the vlan of the port is anything other than 1, the MAC address cannot
be found. I am using Vlan 1 for switch communications.

Should I be communicating to the switch via the same VLAN of this port
and expect different snmp results?

Is there a way to set which VLAN's bridge table gets returned to me?
