Nortel WLAN—Security Switch 2300 Series Command Line Reference
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 WSS.
MAC address of this WSS.
Value of the hello timer interval, in seconds, when this WSS
is the root or is attempting to become the root.
Value of the forwarding delay interval, in seconds, when this
WSS 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 WSS 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 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.
Indicates whether a topology change has been detected by the
switch.
Number of times the topology change has occurred.
MAC address of the bridge from which the WSS last received
a topology change.
Number of times the maximum age parameter was changed
dynamically.
Number of valid port BPDUs received.
Number of expired messages.
Indicates whether the link is oversubscribed.
Indicates whether BPDUs are currently being processed.
