VLAN Mapping
Fig. 17 displays an example of the RDL-3000 VLAN mapping feature. Similar to Label
Switch Router (LSR) in Multi-protocol Label Switching (MPLS), the RDL-3000 PMP
system can map (change) the VLAN tag based on the ingress and egress port. The
VLAN tagging can be specified separately for each Service Group (sector controller port)
and Service (subscriber port).
In this example, the VLAN tag for Service Group 'Voice', and Services 'Voice A' and
'Voice B' are set to VID=3, and the VLAN tag for 'Voice C' is set to VID=777.
Ingress packets with VID=3 received on the sector controller Ethernet port are classified
to the 'Voice Group'. These packets are forwarded over the wireless interface to
members of this Service Group (based on packet destination address). Packets
addressed to subscriber A or B will be tagged with VID=3, while packets addressed to
subscriber C will be tagged with VID=777.

Ingress broadcast and multicast traffic with VID=3 arriving at the sector controller
Ethernet port is classified to the 'Voice' Services Group (VID=3), and be forwarded over
the wireless interface to all group members, and will exit the Ethernet port on Subscriber
A and B tagged with VID=3, and Subscriber C tagged with VID=777.
