Fields in the Bridge Display

Field	Description
addressCount	Number of addresses in the bridge address table at the
	point in time in which you 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 generates 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” later 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.
