Table 62 Output for display spantree statistics (continued)

Field	Description
hold timer	Status of the hold timer. This timer ensures that
	configured BPDUs are not transmitted too frequently
	through any bridge port.
hold timer value	Current value of the hold timer, in seconds.
delay root port timer	Status of the delay root port timer, which enables fast
	convergence when uplink fast convergence is enabled.
delay root port timer	Current value of the delay root port timer.
value
delay root port timer	Whether the delay root port timer has been restarted.
restarted is
spanning tree type	Type of spanning tree. The type is always IEEE.
spanning tree multicast	Destination address used to send out configured BPDUs on
address	a bridge port.
bridge priority	STP priority of this WX switch.
bridge MAC address	MAC address of this WX switch.
bridge hello time	Value of the hello timer interval, in seconds, when this WX
	switch is the root or is attempting to become the root.
bridge forward delay	Value of the forwarding delay interval, in seconds, when
	this WX switch is the root or is attempting to become the
	root.
topology change	Port number that initiated the most recent topology
initiator	change.
last topology change	System time when the most recent topology change
occurred	occurred.
topology change	Value of the topology change flag in configuration BPDUs
	to be transmitted by this WX switch on VLANs for which
	the switch is the designated bridge.
topology change time	Time period, in seconds, during which 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. It is equal to the sum of the switch’s
	maximum age and forwarding delay parameters.
topology change	Indicates whether a topology change has been detected
detected	by the switch.
topology change count	Number of times the topology change has occurred.
topology change last	MAC address of the bridge from which the WX switch last
recvd. from	received a topology change.
