Alcatel Unleashed

Hi,

we have an Cisco2960s, 3750x and OS6450 mixed L2 network here. All switches are running mstp with same mstp config.
we often see STP Topology Changes on "show log swlog":

STP info Topology changed on VLAN/STP id 0

We would like to know the interface where the TC was received to find the root cause. (Like "show spanning-tree detail" on cisco)

Is there any command to identify the Port?
Or should we enable any advanced debug to see it in swlog?

THX!

in the newest releases (since ca. 1 year) you can see the source of the last tc-port with the command "show spantree cist". Before it was only possible with debug commands.
regards
Silvio

YES!

Topology Changes : 566,
Topology age : 02:08:08,
Last TC Rcvd Port : Slot 1 Interface 50,

thank you!
