Creating a 802.1Q Tunnel Port You create the dot1q-tunnel port using the switchport mode command. Note You need to set the 802.1Q tunnel port to an edge port with the spanning-tree port type edge command. The VLAN membership of the port is changed using the switchport access vlan vlan-id command. You should disable IGMP snooping on the access VLAN allocated for the dot1q-tunnel port to allow multicast packets to traverse the Q-in-Q tunnel. BEFORE YOU BEGIN You must first configure the interface as a switchport.
