STP Logging N7k

Hi,

our pair of Nexus7000 are configured with RSTP.

On the Edge-Switches we have seen an STP topology change in all connected vlans.

On N7k the topology has also changed what we`ve only seen in the output of the stp details

sh spanning-tree vlan 46 detail

VLAN0046 is executing the rstp compatible Spanning Tree protocol

  Bridge Identifier has priority 8192, sysid 46, address 0023.04ee.be01

  Configured hello time 2, max age 20, forward delay 15

  We are the root of the spanning tree

  Topology change flag not set, detected flag not set

  Number of topology changes 292 last change occurred 145:31:18 ago

          from port-channel252

  Times:  hold 1, topology change 35, notification 2

          hello 2, max age 20, forward delay 15

  Timers: hello 0, topology change 0, notification 0

I like to configure a logging for topology changes, but i havn't found a command.

Is there an opportunity to get this logging-messages on n7k?

Kind regards

Andreas

In short, I dont think so (not that I have seen), however the log messages generated on the subject of STP are here:

It may help?
