Configuring one-to-one VLAN mapping

About one-to-one VLAN mapping
Configure one-to-one VLAN mapping on the customer-side ports of wiring-closet switches
(see Figure
Procedure
1. Enter system view.
system-view
2. Enter interface view.
Enter Layer 2 Ethernet interface view.
interface interface-type interface-number
Enter Layer 2 aggregate interface view.
interface bridge-aggregation interface-number
3. Set the link type of the port.
port link-type { hybrid | trunk }
By default, the link type of a port is access.
4. Assign the port to the original VLAN and the translated VLAN.
Assign the trunk port to the original VLAN and the translated VLAN.
port trunk permit vlan vlan-id-list
By default, a trunk port is assigned to VLAN 1.
Assign the hybrid port to the original VLAN and the translated VLAN as a tagged member.
port hybrid vlan vlan-id-list tagged
By default, a hybrid port is an untagged member of the VLAN to which the port belongs
when its link type is access.
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.

Configuring many-to-one VLAN mapping

About many-to-one VLAN mapping

address assignment environment
About many-to-one VLAN mapping in dynamic IP address assignment environment
In a network that uses dynamic address assignment, configure many-to-one VLAN mapping with
DHCP snooping.
The switch replaces the SVLAN tag of the downlink traffic with the associated CVLAN tag based on
the DHCP snooping entry lookup.
