If you are familiar with the Cisco IOS CLI, be aware that the Cisco NX-OS commands for this feature
Note
might differ from the Cisco IOS commands that you would use.

Creating a 802.1Q Tunnel Port

You create the dot1q-tunnel port using the switchport mode command.
You need to set the 802.1Q tunnel port to an edge port with the spanning-tree port type edge command.
Note
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.
