Information on the Status Display (the screen shown in Figure 21-9) is
described on p age 20 -23.
Information on the Bridge Port Statistics Display:
●Type/Format – identifies the interface type (Ethernet, Token Ring, or frame
relay) and (if fr a me re la y ) f r a me forma t (Nati ve LL C 2, 8025_SRB, or 80 23_TB,
as configured in the Port record).
●DesignatedRoot – is the br idge selected as Root in the spanning tree. The
selection of root is determined by the bridge with the lowest Bridge ID, which
consi sts of a Bridge Prio rity (described on page 16-5) and MAC address.
●DesignatedBridge – is the bridge connecting to the least-cost path to the root
bridge.
●DlyExceeded – is the number of frames discarded because of excessive delay.
●OutFrames – is the number of transmitted frames.
●InCfgShort – is the number of received Configuration BPDUs (Bridge Protocol
Data Units) th at were dropped because they wer e too short.
●OutCfgBPDU – is the number of transmitted Configuration BPDUs.
●MTUExceeded – is the number of frames discarded because of excessive size.
●InDiscards – is the number of incoming frames that wer e discard ed because t hey
did not match a filter.
●InTcnShort – is the number of received TCN (Topology Change Notification)
BPDUs that were dropped because they were too short.
●OutTcnBPDU – is the number of transmitted TCN BPDUs.
●FwdTrans – is the number of times the Bridge port went from the Learning state
to the Forwardi ng state.
●OutCfgDrop – is the nu mb e r of Configuration BPDUs t hat w ere dropped due t o
a lack of resources.
●InCfgBPDU – is the number of received Configuration BPDUs.
●OutOctets – is the number of transmitted octets.
●InFrames – is the number of received frames.
●OutTcnDrops – is the number of TCN BPDUs that were dropped due to a lack
of resour ces.
●InTcnBPDU – is the number of received TCN BPDUs.
●InOctets – is the number of received octets.
