You can run a bridge (ESM and EFSM) in either Transparent bridging mode
or in Express Switching mode. You can run a Token Ring (TRSM) bridge in
Transparent, Source Route/Transparent (SRT) or Source Route (SR) modes.
The advantages and disadvantages of using Express Switching are defined
in Chapter 6: Express Switching or Chapter 12: Token Ring in the LANplex
System in the LANplex 6000 Operation Guide. The advantages and
disadvantages of using Transparent, Source Route/Transparent or Source
Route modes are defined in Chapter 12: Token Ring in the LANplex System in
the LANplex 6000 Operation Guide.
By default, the bridge is set to run in Transparent bridging mode.
Prior to setting a switching module for Express Switching mode, you must
flush any statically configured addresses. See Chapter 12: Administering
Bridge Ports for more information about flushing addresses.
Description
Peak value of addressCount
Configurable value appended as the most significant portion of a
bridge identifier
Cost of the best path to the root from the root port of the bridge
(for example, one determining factor of cost is the speed of the
network interface — the faster the speed, the smaller the cost)
Port with the best path from the bridge to the root bridge
Configurable parameter that provides the state of the bridge (that
is, whether Spanning Tree is enabled or disabled for that bridge).
The default value is disabled.
Value (in hours, minutes, and seconds) indicating how long since
Spanning Tree last reconfigured the network topology
Indicates whether a topology change is currently occurring on the
bridge. A value of true means that it is. A value of false means that
no topology change is occurring.
Number of times Spanning Tree has reconfigured the network
topology
Indicates whether embedded protocol addresses are being
translated between Token Ring and FDDI ports. Native mode
indicates that translations occurring while backbone indicates that
translation is off.
