User Guidelines
Use the global configuration command
to configure
the inner and outer TPIDs.When dvlan-tunnel is enabled on an interface, the
interface is configured as an uplink or service provider (SP) port. All other
interfaces on the switch behave like access (customer) ports.
Uplink Port Behavior
If a single-tagged (SP tagged) or double-tagged (SP tag as outer tag) packet
ingresses an uplink port, the switch passes it through unchanged to the
respective access or uplink ports.
If an untagged or single tagged (802.1Q tagged) packet ingresses an uplink
If an untagged or single tagged (802.1Q tagged) packet ingresses an uplink
port, the switch tags it with the configured ethertype and service provider
VLAN ID taken from the ingress port PVID.
Access Port Behavior
Ingress packets on an access port are always tagged by the switch. Packets are
tagged on ingress with the configured ethertype and the service provider ID
taken from the PVID. On egress, the access port strips all (SP) tags belonging
to service provider VLANS.
Example
The following example displays how to enable Double VLAN Tunneling at
gigabit ethernet port 1/0/1.
