Parameters

vlan-id translated-vlan vlan-id: Specifies the original VLAN and translated VLAN for a one-to-one VLAN mapping. The value range for the vlan-id argument is 1 to 4094. The original VLAN and the translated VLAN cannot be the same.

all: Deletes all VLAN mapping configurations from the interface.

Usage guidelines

VLAN mapping takes effect only on VLAN-tagged packets received on an interface.

Different one-to-one VLAN mapping entries cannot include the same translated VLANs. If you configure multiple one-to-one VLAN mapping entries for the same original VLANs, the most recent configuration takes effect.

Before you enable or disable QinQ on a port, you must remove all VLAN mappings on the port.

Examples

# Configure a one-to-one VLAN mapping on GigabitEthernet 1/0/1 to map VLAN 1 to VLAN 101.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/1

[Sysname-GigabitEthernet1/0/1] vlan mapping 1 translated-vlan 101
