No dot1qTpFdbEntry object for Cisco Devices

There is this problem with dot1qTpFdbEntry object which doesn't exist when polling mac addresses from Cisco devices.

When using poller.php in verbose mode and executing one of the commands for extracting mac-address-table it gives the error like this:

/usr/bin/snmpbulkwalk -v2c -c <MyCommunity> -OqsX -m Q-BRIDGE-MIB -M /opt/observium/mibs udp:<CiscoSwitch>:161 dot1qTpFdbEntry
dot1qTpFdbEntry No Such Object available on this agent at this OID

Cisco has different OID for that using the BRIDGE-MIB group instead of Q-BRIDGE-MIB (oid 1.3.6.1.2.1.17.4.3.1) but the problem lies that with this OID you are able to extract mac addresses from Vlan 1 - 1001, not from the extended ones.

What can we do about it? (well, apart from replacing Cisco devices )

Thanks,
