If the port is a trunk port then use the following conmmand:

int fa 0/x

no switchport trunk native vlan x

This will revert the native vlan as Vlan1 on the traunk port.

Naidu,

Two ways:

1. Check the interface config " show run int fa 0/x" and check if command " switchport mode trunk " is present.

2.Use the command " show interface fa0/x switchport " to check the operational mode of the switchport.

HTH,Please rate if it does.

Hi Naidu,

Issue a command "sh interface switchport" and it will give you the output like

Switch#sh int gig1/0/23 switchport

Name: Gi1/0/23

Switchport: Enabled

Administrative Mode: trunk

Operational Mode: trunk

Alternatively you can issue a command

"sh interfaces trunk" and it will list all interface which are configured as trunk ports.

HTH
