Table 10-1 Bridge Attributes (continued)

Parameter

Description

 

 

maxAge

The maximum age value at which the stored configuration

 

message information is judged too old and discarded. This value

 

is determined by the root bridge.

mode

Operational mode of the bridge. Valid value is transparent for IEEE

 

802.1d Transparent bridging.

peakAddrCount

Peak value of addressCount

priority

Configurable value appended as the most significant portion of a

 

bridge identifier

rootCost

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)

rootPort

Port with the best path from the bridge to the root bridge

stpGroupAddress

Address that bridge listens to when receiving STP information

stpState

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.

timeSinceLast-

Value (in hours, minutes, and seconds) indicating how long since

TopologyChange

Spanning Tree Protocol last reconfigured the network topology

topologyChange-

Indicates whether a topology change is currently occurring on the

Flag

bridge (true). A value of false means that no topology change is

 

occurring.

topologyChange-

Number of times that Spanning Tree Protocol has reconfigured

Count

the network topology
