Cool ... So you are trying to configure on the switch !!!
Can you pls. provide us " show runn interface <switch prot number > " .
Well I would like to see if "no switchport" is enabled on it .
Pls. Note : dotlq subinterface can be configured only on routed ports .
Switch will not allow you to configure it on L2-ports !!!
For L2 ports you need to configure it as trunk and enable trunk
encapsulation as dot1q !!!
Could you pls. clarify if you are doing this on routed port or switch port .
Thanks and Regards
Arun
