Description
Indicates whether a configured BPDU is to be transmitted
on expiration of the hold timer for the port.
Indicates whether the port is in an inconsistent state.
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.
parentheses indicates the number of configured BPDUs
received by the WX switch for this VLAN's spanning tree.
Number of topology change notification (TCN) BDPUs
transmitted on this port.
Number of TCN BPDUs received on this port.
Number of times the port state transitioned to the
forwarding state.
Number of service control point (SCP) failures.
Number of times the root bridge changed.
State of the loop guard. In the current release, the state is
always FALSE.
Number of loops that have occurred.
Status of the forwarding delay timer. This timer monitors
the time spent by a port in the listening and learning
states.
Current value of the forwarding delay timer, in seconds.
Status of the message age timer. This timer measures the
age of the received protocol information recorded for a
port.
Current value of the message age timer, in seconds.
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.
Current value of the topology change timer, in seconds.
