switch# configure terminal
switch(config)# interface ethernet 7/1
switch(config-if)# switchport
switch(config-if)# switchport dot1q ethertype 0x9100
switch(config-if)# exit
switch(config)# exit
switch# show dot1q-tunnel
Enabling the Layer 2 Protocol Tunnel
You can enable protocol tunneling on the 802.1Q tunnel port.
SUMMARY STEPS
1. configure terminal
2. interface ethernet slot/port
3. switchport
4. switchport mode dot1q-tunnel
5. l2protocol tunnel [cdp | stp | vtp]
6. no l2protocol tunnel [cdp | stp | vtp]
7. exit
8. copy running-config startup-config
DETAILED STEPS
