P2p *PVID issue in IE3300 Switch

[Himanshu_Dwivedi]

I have an complex architecture where two switches IE3300(17.12.04) are connected to each other over the trunk and the configuration is sime as below

int G1/1

switchport mode trunk

switchport nonegotiate

It is showing port in Broken BKN and P2p PVID* , I know it might be due to native VLAN mismatch, but the config is very simple. I tried to flush the config on interface and again reconfig it but same issue. I tried putting BPDU filter on both the switch port it start working but both the switch act as root bridge also may lead STP loop, so remove BPDUFILTER.

Can anyone share the suggestion

Hello @Himanshu_Dwivedi ,

try to configure manually a native VLAN on both sides of the trunk link

switchport trunk native vlan 999

for example , use an existing VLAN in your environment or create a new one to dedicate to this purpose.

Hope to help
