Hi Asif,

Hi Asif,

May be you need to define trunk encapsulation method.

Please check.

If possible, please paste output of show interface <interface name> switchport

Asif,

Asif,

Looks like I misread your question - Can you tell me if you are not able to configure vlan and allow that vlan in trunk interface.

or you are able to configure all these and they are not showing up in running configuration?
