Appendix B: Mapping PVCs to VLANs

RTL867x device supports mapping ATM Permanent Virtual Circuits (PVCs) to VLANs,
based on the ATM bridging standards of RFC 2684. This feature allows an ATM PVC to be
configured as a bridging interface and used in conjunction with a VLAN. The function is
supported only if the device is equipped with a RTL8205SC, which is a 5-port 10/100MBps
switch controller.
Figure B.1 illustrates the how the RTL867x device adds a VLAN ID and tag to packets
subject to PVC-VLAN mapping. In this example, vc3 is mapped to VLAN 20. The RTL867x
device adds VLAN ID 20 and tag 8100 to packets from vc3.
