I am trying to enable PVST+ on our Black Diamond switch.
When I try to enable certain STP instances, I get an error:
Ops_BD8810.2 # configure stpd AB-Level2 tag 2602 Ops_BD8810.3 # enable stpd AB-Level2 Error: Incorrect carrier vlan configuration of port 4:41 in stp domain AB-Level2 Configuration failed on backup MSM, command execution aborted! I am not sure why this happens, seems to not have a problem with port 2:9:
