Command Usage
◆
QinQ tunneling must be enabled on the switch using the
dot1q-tunnel
system-tunnel-control
command before the
switchport dot1q-tunnel mode
interface command can take effect.
◆
When a tunnel uplink port receives a packet from a customer, the customer tag
(regardless of whether there are one or more tag layers) is retained in the inner
tag, and the service provider’s tag added to the outer tag.
◆
When a tunnel uplink port receives a packet from the service provider, the
outer service provider’s tag is stripped off, and the packet passed on to the
VLAN indicated by the inner tag. If no inner tag is found, the packet is passed
onto the native VLAN defined for the uplink port.
Example
Console(config)#interface ethernet 1/1
Console(config-if)#switchport dot1q-tunnel mode access
Console(config-if)#
