Token Ring ports are capable of running at 4 or 16 mbps, and either half- or full-duplex.
Token Ring ports can operate as Token Ring concentrators or as end stations.
The following bridging modes are supported:
Routing Information Fields (RIFs) forward packets from rings to bridges, instead of learning MAC addresses. Both the IBM and IEEE STPs are supported.
SRB is combined with transparent bridging. Packets with a RIF are forwarded through SRB, whereas packets without a RIF are forwarded through transparent bridging. Only the IEEE STP is supported.
Packets can be forwarded based on MAC addresses or RIFs.
