Step Command Remarks
3. Configure the link type of the
port.
• Configure the port as a trunk
port:
port link-type trunk
• Configure the port as a hybrid
port:
port link-type hybrid
The default link type of an Ethernet
port is access.
4. Assign the port to all SVLANs.
• As a trunk port:
port trunk permit vlan
{ vlan-id-list | all }
• As a hybrid port:
port hybrid vlan vlan-id-list
tagged
By default:
• A trunk port is assigned to only
VLAN 1.
• A hybrid port is an untagged
member of VLAN 1.
Configuring two-to-two VLAN mapping
Perform two-to-two VLAN mapping on an edge device that connects two SP networks, for example, on
PE 2 (edge device of the SP 1 network) and PE 3 (edge device of the SP 2 network) in Figure 49 . The
two-to-two VLAN mapping implementation of the switch enables two remote sites in the same VLAN to
communicate at Layer 2 across two service provider networks that use different VLAN assignment
schemes.
In two-to-two VLAN mapping, foreign SVLANs refer to the outer VLANs of double-tagged frames that
arrive at the customer-side port, local VLANs refer to VLANs that replace the foreign SVLANs, and
CVLANs refer to inner VLANs.
Perform these tasks to configure two-to-two VLAN mapping:
Task Description
Configuring an uplink policy for the
customer-side port Replaces foreign SVLANs with local SVLANs for uplink traffic
(required).
Configuring the customer-side port
Configures VLAN and other settings required for two-to-two VLAN
mapping (required).
Configuring the network-side port
Configures VLAN and other settings required for two-to-two VLAN
mapping (required).
Configuring an uplink policy for the customer-side port
The uplink policy on the customer-side port changes the SVLAN ID of incoming traffic.
To configure an uplink policy for the customer-side port:
