nonvolatile RAM so they will survive a power loss or system initialization. Source Routed traffic is not forwarded while in this mode.
Source Routing (SR)
In Source Routing (SR), the packet contains information in the Route Information Field (RIF), which specifies the route the packet should follow in order to reach its destination. Through the process of route discovery, the packet determines various routes available and embeds this information as Ring Numbers and Bridge Numbers within the RIF. The bridge compares the RIF to its configured Bridge Numbers and Ring Numbers for each port and forwards the packet if appropriate. The TRSM utilizes one hop between any two ports on the module.
For Spanning Tree, the network mesh topology is reduced to a single path utilizing IEEE 802.1d Spanning Tree.
Transparent traffic is not forwarded while in this mode.

To configure the Bridging mode, see Chapter 11: Administering the Bridge in the LANplex 6000 Administration Console User Guide. N
TRSM Configurable Protocol addresses on Token Ring are defined in
Modes communicate with a server on FDDI, it is necessary to reformat or translate these embedded protocol address. The TRSM supports translation between Token Ring and FDDI for the following protocols: IP, IPX, NetBIOS, and SNA.
Translation is not necessary if FDDI is only used as a transport media between TRSMs. Since this feature may degrade performance, it is recommended that you disable the translation feature when FDDI is used solely as a transport media.
