Description
Status of the hold timer. This timer ensures that
configured BPDUs are not transmitted too frequently
through any bridge port.
Current value of the hold timer, in seconds.
Status of the delay root port timer, which enables fast
convergence when uplink fast convergence is enabled.
Current value of the delay root port timer.
Whether the delay root port timer has been restarted.
Type of spanning tree. The type is always IEEE.
Destination address used to send out configured BPDUs on
a bridge port.
STP priority of this WX switch.
MAC address of this WX switch.
Value of the hello timer interval, in seconds, when this WX
switch is the root or is attempting to become the root.
Value of the forwarding delay interval, in seconds, when
this WX switch is the root or is attempting to become the
root.
Port number that initiated the most recent topology
change.
System time when the most recent topology change
occurred.
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.
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.
Indicates whether a topology change has been detected
by the switch.
MAC address of the bridge from which the WX switch last
received a topology change.
Number of times the maximum age parameter was
changed dynamically.
