Table 4: Output for show 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 value	Current value of the delay root port timer.
delay root port timer restarted is	Whether the delay root port timer has been restarted.
spanning tree type	Type of spanning tree. The type is always IEEE.
spanning tree multicast address	Destination address used to send out configured BPDUs on a
	bridge port.
bridge priority	STP priority of this WSS.
bridge MAC address	MAC address of this WSS.
bridge hello time	Value of the hello timer interval, in seconds, when this WSS
	is the root or is attempting to become the root.
bridge forward delay	Value of the forwarding delay interval, in seconds, when this
	WSS is the root or is attempting to become the root.
topology change initiator	Port number that initiated the most recent topology change.
last topology change occurred	System time when the most recent topology change occurred.
topology change	Value of the topology change flag in configuration BPDUs to
	be transmitted by this WSS 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 WSS
	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 detected	Indicates whether a topology change has been detected by the
	switch.
topology change count	Number of times the topology change has occurred.
topology change last recvd. from	MAC address of the bridge from which the WSS last received
	a topology change.
dynamic max age transition	Number of times the maximum age parameter was changed
	dynamically.
port BPDU ok count	Number of valid port BPDUs received.
msg age expiry count	Number of expired messages.
link loading	Indicates whether the link is oversubscribed.
BPDU in processing	Indicates whether BPDUs are currently being processed.
