Description
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.
Maximum number of addresses that can be stored in the
bridge address table.
Configurable reporting threshold for the total number of
addresses known on this bridge. When this threshold is
reached, the module 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, see "bridge
addressThreshold" later in this chapter.
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.
Configurable time period in seconds that the bridge
spends in each of two STP 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.
