Step Command Remarks
4. Assign the port to the
SVLANs.
• As a hybrid port:
port hybrid vlan vlan-id-list tagged
• As a trunk port:
port trunk permit vlan { vlan-id-list |
all }
By default, ports of any link
type permit VLAN 1.
Configuring one-to-two VLAN mapping
Perform one-to-two VLAN mapping on the edge switches from which customer traffic enters SP networks,
on PE 1 and PE 4 in
Figure 49 for example. One-to-two VLAN mapping enables the edge devices to
insert an outer VLAN tag to each incoming VLAN-tagged packet.
Perform these tasks to configure one-to-two VLAN mapping:
Task Description
Configuring an uplink policy Configures an uplink policy for the customer-side port (required).
Configuring the customer-side port
Configures VLAN and other settings required for one-to-two VLAN
mapping (required).
Configuring the network-side port
Configures VLAN and other settings required for one-to-two VLAN
mapping (required).
Configuration prerequisites
Create VLANs, and plan CVLAN-to-SVLAN mappings.
Configuring an uplink policy
To configure an uplink policy to insert an SVLAN to VLAN tagged packets:
Step Command Remarks
1. Enter system view. system-view N/A
2. Configure one class for a
CVLAN.
a. Create a class and enter
class view:
traffic classifier tcl-name
[ operator { and | or } ]
b. Specify one CVLAN as the
match criterion:
if-match service-vlan-id
vlan-id-value
c. Return to system view:
quit
