The Number of Ports object corresponds to the Dot1dBaseNumPorts MIB object of the
dot1dBase group. This read-only object displays the number of ports the bridge
controls.
The Bridge Type object corresponds to the Dot1dBaseType MIB object of the
dot1dBase group. This read-only object indicates what type of bridging this bridge can
perform (for example, transparent only, source route only, or srt).
The Learned Entry Discarded object corresponds to the Dot1dTpLearned-
EntryDiscards MIB object of the dot1dTp group. This read-only object displays the
number of forwarding database entries, which have been or could have been learned,
but were discarded due to lack of space in the mentioned database. A high value for

The Index column displays the corresponding index number of each entry.
The Port column corresponds to the Dot1dBasePort MIB object of the dot1dBase
group. This read-only object identifies the port for which this entry pertains.
The IFIndex column corresponds to the Dot1dBasePortIfIndex MIB object of the
dot1dBase group. This read-only object displays the value of the IfIndex object instance
(defined in MIB-II) for the interface corresponding to this port.
The Circuit column corresponds to the Dot1dBasePortCircuit MIB object of the
dot1dBase group. This read-only object displays the name of an object instance unique
for the port when this port has the same dot1dBasePortIfIndex value as another port on
the bridge.
The DelayExceedDiscards column corresponds to the Dot1dBasePort-
DelayExceededDiscards MIB object of the dot1dBase group. This read-only object
