498 CHAPTER 12: STP COMMANDS
config_pending Indicates whether a configured BPDU is to be transmitted
on expiration of the hold timer for the port.
port_inconsistency Indicates whether the port is in an inconsistent state.
config BPDU’s xmitted Number of BPDUs transmitted from the port. A number in
parentheses indicates the number of configured BPDUs
transmitted by the WX switch for this VLAN’s spanning
tree.
config BPDU’s received Number of BPDUs received by this port. A number in
parentheses indicates the number of configured BPDUs
received by the WX switch for this VLAN’s spanning tree.
tcn BPDU’s xmitted Number of topology change notification (TCN) BDPUs
transmitted on this port.
tcn BPDU’s received Number of TCN BPDUs received on this port.
forward transition
count
Number of times the port state transitioned to the
forwarding state.
scp failure count Number of service control point (SCP) failures.
root inc trans count Number of times the root bridge changed.
inhibit loopguard State of the loop guard. In the current release, the state is
always FALSE.
loop inc trans count Number of loops that have occurred.
forward delay timer Status of the forwarding delay timer. This timer monitors
the time spent by a port in the listening and learning
states.
forward delay timer
value
Current value of the forwarding delay timer, in seconds.
message age timer Status of the message age timer. This timer measures the
age of the received protocol information recorded for a
port.
message age timer
value
Current value of the message age timer, in seconds.
topology change timer Status of the topology change timer. This timer determines
the time period during which configured BPDUs are
transmitted with the topology change flag set by this WX
switch when it is the root bridge, after detection of a
topology change.
topology change timer
value
Current value of the topology change timer, in seconds.
