maxAge
Time period in seconds that the bridge uses to discard
stored configuration messages. The value is determined
by the root bridge. Compare with the
bridgeMaxAge
field.
mode
Reflects that the bridge operates as a transparent bridge.
peakAddrCount
Reflects the highest number of addresses that have been
counted since the last address table flush. For the current
size of the address table, see the
addressCount
field.
priority
Configurable STP priority value for the bridge. The default
value is 0x8000. (0x signifies that 8000 is a hexadecimal
number.) The acceptable range is 0x0 – 0xffff (0 – ffff). To
configure a value, see “bridge spanningTree stpPriority”
later in this chapter. The bridge priority is included in the
bridge identifier and is considered the most significant
portion because it influences root bridge selection. A
lower priority increases the odds that the bridge will
become the root bridge.
rootCost
Value that reflects the total cost of the best path (lowest
value) from the bridge root port to the root bridge. The
value sums individual port path costs. To configure path
costs for ports on the bridge, see “bridge port stpCost” in
Chapter 10.
rootPort
Logical port with the best path from the bridge to the root
bridge.
stpGroupAddress
Address to which the bridge listens to receive
configuration messages and other STP information. To
modify the STP group address, see “bridge spanningTree
stpGroupAddress” later in this chapter.
stpState
Whether the Spanning Tree Protocol is enabled or
disabled for the bridge. The default value is disabled for all
switches except CoreBuilder 9000 modules. To configure
the bridge STP state, see “bridge spanningTree stpState”
later in this chapter. (STP is also configured on a
port-by-port basis. See “bridge port stpState”
in
Chapter 10.)
timeSinceLastTopology
Change
Time elapsed (in hours, minutes, and seconds) since STP
last reconfigured the network topology.
topologyChangeCount
Number of times that STP has reconfigured the network
topology since you enabled STP or rebooted the system
(whichever is less).
topologyChangeFlag
Whether the bridge topology is currently changing
(true)
or not changing
(false)
