Fields in the Bridge Display
Field Description
addressCount Number of addresses in the bridge address table at the
point in time in which yo u are viewing it. This value
fluctuates but the highest value reached is recorded in the
PeakAddrCount field.
addrTableSize Maximum number of addresses that can be stored in the
bridge address table. For CoreBuilder® switches, the value
is 32K. For SuperStack® II Switches, the value is 16K.
addrThreshold Configurable reporting threshold for the total number of
addresses known on this bridge. When this threshold is
reached, the system genera tes the SNMP trap
addressThresholdEvent. The range of valid values for
setting this object is between 1 and 1 plus the maximum
table size. To configure this value for the 3500 and 9000
L3 modules, see “bridge addressThreshold” later in this
chapter. This option is not available for the 3900, 9300,
9400 and 9000 L2 modules at this release.
agingTime Configurable time period in seconds that the bridge uses
to age out dynamic addresses except when a topology
change has occurred. (After a topology change, the
bridge uses the value shown in the forwardDelay field
instead until it receives configuration messages without
the topology change flag set). The default value for
agingTime is 300 seconds. The acceptable range is
10– 1,000,000. You can also enter 0 to disable aging. To
configure this value, see “bridge agingTime” la ter in this
chapter.
bridgeFwdDelay Configurable time period in seconds that the bridge
spends in each of two states — listening and learning —
before it transitions to the forwarding state, provided that
the bridge is the root bridge. (If the bridge is not the root
bridge, the bridge uses the value shown in the fwdDelay
field that is assigned to it by the root bridge.) The default
value is 15 seconds. The acceptable range is 4– 30
seconds. To configure the bridge forward delay, see
“bridge spanningTree stpForwardDelay” later in this
chapter.
