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
Vlan 1234
spanning tree enabled protocol rstp
Root ID Priority 32768
Address xxxx.xxxx.xxxx

=====SG-350=====
1) #sh run:

2) #sh spanning-tree active
Root ID Priority 32768

This switch is the root

gi2 enabled 128.2 20000 Frw Desg No P2p (rpvst)
* 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!

can you post show vlan, show spann vlan xx from both ?

spanning-tree portfast default
spanning-tree portfast bpduguard
remove the portfast + bpduguard from global mode and config it in interface mode.
this is the cause of issue I think

Hello
Confirm all non trunks ports (edge ports) have stp portfast enabled and have an administrative status of access ( so making sure those access ports are not able to create a trunk dynamically - so disabling DTP)
show interface trunks
show interface switchport
