Task Switch role
Configuring two-to-two VLAN mapping Edge switch between SP networks
Configuring one-to-one VLAN mapping
Perform one-to-one VLAN mapping on wiring-closet switches (see Figure 63 ) to isolate traffic by both user
and traffic type.
Perform these tasks to configure one-to-one VLAN mapping:
Task Description
Configuring an uplink policy Creates CVLAN-to-SVLAN mappings (required).
Configuring a downlink policy Creates SVLAN-to-CVLAN mappings (required).
Configuring the customer-side port Configures settings required for one-to-one VLAN mapping (required).
Configuring the network-side port Configures VLAN settings required for normal communication (required).
Configuration prerequisites
Create CVLANs and SVLANs, and plan CVLAN-SVLAN mappings.
Configuring an uplink policy
Follow these steps to configure an uplink policy to map each CVLAN to a unique SVLAN:
To do... Use the command... Remarks
Enter system view system-view —
Create a class and enter class
view traffic classifier tcl-name [ operator
{ and | or } ]
Specify a CVLAN as the match
criterion
if-match customer-vlan-id vlan-id
Return to system view quit
Required
Repeat these steps to configure one
class for each CVLAN.
Create a traffic behavior and enter
traffic behavior view
traffic behavior behavior-name
Configure an SVLAN marking
action
remark service-vlan-id vlan-id
Return to system view quit
Required
Repeat these steps to configure one
behavior for each SVLAN.
Create a QoS policy and enter
QoS policy view
qos policy policy-name Required
Associate the class with the
behavior to map the CVLAN to the
SVLAN
classifier tcl-name behavior
behavior-name
Required
Repeat this step to create other
CVLAN-to-SVLAN mappings.
Configuring a downlink policy
Follow these steps to configure a downlink policy to map SVLANs back to CVLANs:
To do... Use the command... Remarks
