Double VLAN Commands
This section describes the commands you use to configure double VLAN (DVLAN). Double VLAN
tagging is a way to pass VLAN traffic from one customer domain to another through a Metro
Core in a simple and cost effective manner. The additional tag on the traffic helps differentiate
between customers in the MAN while preserving the VLAN identification of the individual
customers when they enter their own 802.1Q domain.
dvlan-tunnel ethertype
This command configures the ether-type for all interfaces. The ether-type may have the values
802.1Q, vMAN, or custom. If the ether-type has a value of custom, the optional value of the
custom ether type must be set to a value from 0 to 65535.
mode dot1q-tunnel
This command is used to enable Double VLAN Tunneling on the specified interface.
no mode dot1q-tunnel
This command is used to disable Double VLAN Tunneling on the specified interface. By default,
Double VLAN T
unneling is disabled.
