Hi All,

Are there any options / commands for troubleshooting spanning tree even if it is just seeing sent / received BPDU's? I have one hop with a Cisco switch running RPVST with a Netonix switch RSTP and 2 links between them 1 Airfibre and 1 Aviat WTM4200 with the WTM set as preferred using STP costs which works elsewhere but not on these links.

Regards
Simon

In the cli you can use the command
Code: Select all
show stp


The STP tab in the web UI is also fairly comprehensive.

If you want to see BPDU frames, you should mirror the port and look at those with wireshark.

Hi Guys,
Thanks, bit of a delayed reply. I was afraid I was going to have to mirror the port but was hoping there was a way around it I guess not to be though.
