Configuring VLAN mapping

Overview

VLAN mapping re-marks VLAN tagged traffic with new VLAN IDs. H3C provides the following types of

VLAN mapping:

One-to-one VLAN mapping—Replaces one VLAN tag with another.

Many-to-one VLAN mapping—Replaces multiple VLAN tags with the same VLAN tag.

One-to-two VLAN mapping—Tags single-tagged packets with an outer VLAN tag.

Two-to-two VLAN mapping—Replaces the SVLAN ID, CVLAN ID, or both IDs for an incoming
double-tagged frame.

mapping
