Configuring 802.1Q Tunneling
Configuring 802.1Q Tunnel Ports
To configure 802.1Q tunneling on a port, perform this task:
Command
Step 1
Router(config)# interface type
Step 2
Router(config-if)# switchport
Step 3
Router(config-if)# switchport mode dot1qtunnel
Router(config-if)# no switchport mode dot1qtunnel
Step 4
Router(config-if)# end
Step 5
Router# show dot1q-tunnel [{interface type
interface-number}]
1.
type = ethernet, fastethernet, gigabitethernet, or tengigabitethernet
This example shows how to configure tunneling on port 4/1 and verify the configuration:
Router# configure terminal
Router(config)# interface fastethernet 4/1
Router(config-if)# switchport mode dot1qtunnel
Router(config-if)# end
Router# show dot1q-tunnel interface
Configuring the Cisco 7600 Series Router to Tag Native VLAN Traffic
The vlan dot1q tag native command is a global command that configures the router to tag native VLAN
traffic, and admit only 802.1Q tagged frames on 802.1Q trunks, dropping any untagged traffic, including
untagged traffic in the native VLAN.
To configure the router to tag traffic in the native VLAN, perform this task:
Command
Step 1
Router(config)# vlan dot1q tag native
Router(config)# no vlan dot1q tag native
Step 2
Router(config)# end
Step 3
Router# show vlan dot1q tag native
This example shows how to configure the switch to tag native VLAN traffic and verify the configuration:
Router# configure terminal
Router(config)# vlan dot1q tag native
Router(config)# end
Router# show vlan dot1q tag native
