Hi all,
I have 2 Switches (Catalyst 9200 & SG-350). Both are connected with Trunk port. I am making SG-350 my root switch running on Rapid-Pvst. Configurations as follows:
=====Catalyst 9200=====
1) #sh run:
spanning-tree mode rapid-pvst
spanning-tree portfast default
spanning-tree portfast bpduguard
spanning-tree extend system-id
2) #sh spanning-tree active

* Port Type or PVID Inconsistency // Warning I am trying to get rid of
=====End=====
I am encountering "* Port Type or PVID Inconsistency" , however when I run #sh spanning-tree inconsistency, no ports showed up as inconsistent. My network is still functioning as per normal but I am worried that "* Port Type or PVID Inconsistency" may cause issues in future.
Troubleshooting methods I have tried:
1) Shut and no shut the trunk port
2) Change both switches to pvst instead of rapid-pvst
Could it be because of the MAC address format is different for both switch? Any advice is greatly appreciated. Thanks!
