* Port Type or PVID Inconsistency

[antotini]

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
Cost 4
Port 1(GIgabitEthernet 1/0/1)
Hello Time 2 sec Max Age 20 Sec Forward Delay 15 sec
Bridge ID Priority 34002 (priority 32768 sys_id ext 1234)
Address yyyy.yyyy.yyyy
Hello Time 2 sec Max Age 20 Sec Forward Delay 15 sec

Interface Role Sts Cost Prio.Nbr Type
--------- ---- --- ---- -------- -----
Gi1/0/1 Root Fwd 4 128.1 P2p

=====SG-350=====
1) #sh run:
spanning-tree mode rapid-pvst

2) #sh spanning-tree active
Root ID Priority 32768
Address xx.xx.xx.xx.xx.xx
This switch is the root
Hello Time 2 sec Max Age 20 Sec Forward Delay 15 sec

Name State Prior.Nbr Cost Sts Role PortFast Type
----- ----- ----- ----- ----- ----- ----- -----
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!

is the VLAN same on other side in CBS 350 ? is the only 2 switches connected in the network, how is your topology looks like ?

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

Hi guys, thank you for your responses. 

@balaji.bandi my network topology is SG-350 <=======> Catalyst 9200L on Ethernet ports. 
Both switches are Trunk with the same sets of vlans.

@MHM Cisco World I have removed the global config however the situtation is the same 

[balaji.bandi]

what is the config on the ports connected to each other? and post complete logs from both switches.

show run interface x/x (post from both the switches connected ports)

[MHM Cisco World]

P2P (rpvst) <<- this issue here, 
you run RPVST in 9200 side and rrun RSTP in SG-350

[paul driver]

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
