Configuring VLAN Retagging

Configuring VLAN retagging on a Layer 2 trunk interface requires a one-to-one mapping of the incoming and internal VLAN identifiers.

In the following example, a Layer 2 trunk interface is configured to receive packets with VLAN identifiers 1 through 10. Packets that arrive on the interface with VLAN identifier 11 are retagged with VLAN identifier 2. Before exiting the trunk interface, VLAN identifier 2 in the retagged packets is replaced with VLAN identifier 11.

You can use either J-Web or the CLI configuration editor to configure VLAN retagging.
