STP Commands 421
Nortel WLAN—Security Switch 2300 Series Command Line Reference
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.
