VLAN Translation (Normalization)

A packet received on a physical port is only accepted for processing if the VLAN tags of the received packet match the VLAN tags associated with one of the logical interfaces configured on the physical port. The VLAN tags of the received packet are translated only if they are different than the normalized VLAN tags. For the translation case, the vlan-id or vlan-tags statements specify the normalized VLAN. For this case, the terms “learn VLAN” and “normalized VLAN” can be used interchangeably.

Specify the normalized VLAN using one of the following configuration statements:

vlan-id vlan-number
vlan-id none
vlan-tags outer outer-vlan-number inner inner-vlan-number

Configured the normalized VLAN for one of the following scenarios:

Implicit VLAN Translation to a Normalized VLAN
Sending Tagged or Untagged Packets over VPLS Virtual Interfaces
