Currently in the process of correcting a spanning tree mis-configuration, predominantly caused by ports not correctly configured as edge ports.
Currently seeing a lot of spanning tree TCN's on the core, but need to workout whereabouts, or what port are they coming in from.
Currently have the following added to the defaultfilter
configure log filter DefaultFilter add events STP.SendClntTopoChgMsg
Which is producing the following log entries multiple times:
11/12/2015 15:48:00.06 <Summ:STP.SendClntTopoChgMsg> Send topology change notification type 2 for STPD STP_Data
Have tried enabled various other logs like stp dump and trace logs, but nothing is telling where they are coming from.
Aside from a packet capture, is there anyway to do this?
Many thanks in advance.
