X = Mapped CoS from internal priority (X contributes to internal priority) using CoS encode

Specifying Local VPLS endpoints
Local VPLS can be configured between any combination of dual-tagged, single-tagged, and
untagged endpoints.
The following procedures describe how to configure VPLS endpoints:
• “Configuring an untagged endpoint”
• “Configuring a single-tagged endpoint”
• “Configuring a dual-tagged endpoint”
Configuring an untagged endpoint
To configure untagged port 1/1 into Local VPLS instance “test1”, use the following commands.
Brocade(config)# router mpls
Brocade(config-mpls)# vpls test1 5000
Brocade(config-mpls)# vlan 100
Brocade(config-mpls-vpls-test1)# untagged ethernet 1/1
Syntax: [no] untagged ethernet slot /port / vpls-id
The vpls-id variable is the ID of a VPLS instance.
Configuring a single-tagged endpoint
Tagged ports are configured under a VLAN ID. This VLAN ID is only meaningful for the tagged port.
For tagged ports, a vlan-id, port variable pair constitutes a VPLS endpoint. When a port is currently
a member of a non-default VLAN as an untagged port, it must be returned to the default VLAN
before it can be assigned to a VPLS as a tagged port.
To configure a tagged port 1/2 with VLAN 200 into Local VPLS instance “test1”, use the following
commands.
