This chapter shows you how to configure VLAN mapping on the Switch.
28.1 VLAN Mapping Overview
With VLAN mapping enabled, the Switch can map the VLAN ID and priority level of packets received
from a private network to those used in the service provider's network.
The Switch checks incoming traffic from the switch ports (non-management ports) against the
VLAN mapping table first, the MAC learning table and then the VLAN table before forwarding them
through the Gigabit uplink port. When VLAN mapping is enabled, the Switch forwards the tagged
packets according to its VLAN tag that do not match an entry in the VLAN mapping table. If the
incoming packets are untagged, the Switch adds a PVID based on the VLAN setting.
Note: You can not enable VLAN mapping and VLAN stacking at the same time.
28.1.1 VLAN Mapping Example
In the following example figure, packets that carry VLAN ID 12 and are received on port 3 match a
pre-configured VLAN mapping rule. The Switch translates the VLAN ID from 12 into 123 before
forwarding the packets. Any packets carrying a VLAN tag other than 12 (such as 10) and received
on port 3 will be forwarded in the individual VLAN network respectively (such as VLAN 10).
