We use following command for QinQ(dot1q tunneling).
switchport access vlan 75
switchport mode dot1q-tunnel
what ever the packet coming into this port will be tagged with vlan 75 as outer vlan.
But my requirment deffers slitly from this. I need to have an dot1q tunnel port for a range of vlans. For remaining vlans the port should act as trunk port (only allowing the tagged packet, no outer vlan tagging).
