6.7.2 VLAN Mapping
VLAN Mapping function allows the VLAN TAG of the packets to be replaced with the new VLAN
TAG according to the VLAN Mapping entries. And these packets can be forwarded in the new
VLAN. If VLAN VPN function is enabled, a received packet already carrying a VLAN tag will be
tagged basing on the VLAN Mapping entries and becomes a double-tagged packet to be
forwarded in the new VLAN.
