Tasks at a glance Remarks
Configuring many-to-one VLAN mapping
• Configuring many-to-one VLAN mapping in a
network with dynamic IP address assignment
• Configuring many-to-one VLAN mapping in a
network with static IP address assignment
Configure many-to-one VLAN mapping on the campus
switch, as shown in
Figure 62 .
Complete one of the tasks based on the IP address
assignment method.
• Configuring one-to-two VLAN mapping
Configure one-to-two VLAN mapping on PE 1 and PE
4, as shown in
Figure 63 , through which traffic from
customer networks enter the service provider
networks.
Configuring two-to-two VLAN mapping
Configure two-to-two VLAN mapping on PE 3, as
shown in
Figure 63 , which is an edge device of the SP
2 network.
Configuring one-to-one VLAN mapping
Configure one-to-one VLAN mapping on the customer-side ports of wiring-closet switches (see Figure 62 )
to isolate traffic of the same service type from different homes.
Before you configure one-to-one VLAN mapping, create the original VLAN and the translated VLAN.
To configure one-to-one VLAN mapping:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter Layer 2 Ethernet
interface view or Layer 2
aggregate interface view.
• Enter Layer 2 Ethernet interface
view:
interface interface-type
interface-number
• Enter Layer 2 aggregate interface
view:
interface bridge-aggregation
interface-number
N/A
3. Set 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
By default, the link type of a
port is access.
4. Assign the port to the original
VLANs and the translated
VLANs.
• port trunk permit vlan vlan-id-list
• port hybrid vlan vlan-id-list tagged
N/A
5. Configure a one-to-one VLAN
mapping. vlan mapping vlan-id translated-vlan
vlan-id By default, no VLAN mapping
is configured on an interface.
