The following error is filling up the logs. Port 1:45 is the uplink port to another extreme switch. I am unable to find a solution for this. Need assistance.
Slot-1: Port=1:45: No associated STP port for STP Domain tag 10 (Rate-limited)
I can share more details if needed.

Can you point me to a doc which explains configuring extreme switch for pvst+ ?

Mostly happens due to mismatch in stp configuration .
easiest way is to capture the bpdu packet and see why there is a mismatch
and then fix it.[please use TCPdump or do port mirroring]
sometimes if we receive a bpdu from 3rd party switches cisco [pvst].
its a bpdu which is not understood by extreme so we get the error.
Note : pvst+ is understood by extreme if we have the extreme switch configured for pvst+

Hi Jeevan,
Since both of these switches are running STP, most likely there is a mismatch in the carrier vlan configured for the spanning tree domain. Is the switch on the other end seeing a similar log message?

Yes, both this switch and the neighbor are running STP.

Hello Jeevan
It looks as if the switch is receiving a STP BPDU fro the uplink port. Is the switch that it is connected to running STP?
Thanks
