3com WX4400 3CRWX440095A Manual De Usuario

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 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 
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 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 
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 WX switch last 
received a topology change.

dynamic max age 
transition

Number of times the maximum age parameter was 
changed dynamically.
