Port Mode.

Default:

Dot1q-tunnel function disabled on the port by default.

Usage Guide:

After enabling dot1q-tunnel on the port, data packets without VLAN tag (referred to as tag) will be

packed with a tag when entering through the port; those with tag will be packed with an external tag.

The TPID in the tag is 8100 and the VLAN ID is the VLAN ID the port belongs to. Data packets with

double tags will be forwarded according to MAC address and external tag, till the external tag is

removed when transmitted outside from the access port. Since the length of the data packet may be

over sized when packed with external tag, it is recommended to use this command associating the

Jumbo function. Normally this command is used on access ports, and also on trunk ports however

only when associating the VLAN translation function. This command and dot1q-tunnel tpid are

mutually exclusive.

Example:

Join port1 into VLAN3, enable dot1q-tunnel function.

Switch(Config-Vlan3)#exit
