Your logs show:<br>

<br>
This means that bridge port id 5009 with VLAN id 3210 is populated with <br>
3 MAC addresses: 60def3754c4a, e09796484fb0 and e09796484fbb.<br>
<br>
Separate to this, the switch also reports:<br>
<br>
> % snmpwalk -c XX -v2c columba .1.3.6.1.2.1.2.2.1.2<br>
> IF-MIB::ifDescr.5009 = STRING: xe9<br>
<br>
This means that switch interface 5009 is associated with physical <br>
interface xe9.<br>
<br>
The important thing here is that the SNMP bridge port ID is not the same <br>
as the switch interface ID. These two ID numbers should be linked using <br>
the dot1dBasePortIfIndex OID, which shows:<br>
<br>
> SNMPv2-SMI::mib-2.17.1.4.1.2.9 = INTEGER: 5009<br>
<br>
This is wrong, because the .9 doesn't match the value from <br>
dot1qTpFdbPort above.<br>
<br>
So OcNOS should be reporting either:<br>

or more probably:<br>

You should open up a ticket with IP Infusion about this, and refer to <br>
the following document for how the BRIDGE-MIB indexing mechanism works:<br>

<br>
OcNOS's implementation of Q-BRIDGE-MIB should work the same way as <br>
BRIDGE-MIB which is described in that document.<br>
