Specifications

RoamAbout Mobility System Software Command Line Reference 12-31
config_pending Indicates whether a configured BPDU is to be transmitted on expiration of
the hold timer for the port.
port_inconsistency Indicates whether the port is in an inconsistent state.
config BPDU’s xmitted Number of BPDUs transmitted from the port. A number in parentheses
indicates the number of configured BPDUs transmitted by the
RoamAbout switch for this VLAN’s spanning tree.
config BPDU’s received Number of BPDUs received by this port. A number in parentheses
indicates the number of configured BPDUs received by the RoamAbout
switch for this VLAN’s spanning tree.
tcn BPDU’s xmitted Number of topology change notification (TCN) BDPUs transmitted on this
port.
tcn BPDU’s received Number of TCN BPDUs received on this port.
forward transition count Number of times the port state transitioned to the forwarding state.
scp failure count Number of service control point (SCP) failures.
root inc trans count Number of times the root bridge changed.
inhibit loopguard State of the loop guard. In the current release, the state is always FALSE.
loop inc trans count Number of loops that have occurred.
forward delay timer Status of the forwarding delay timer. This timer monitors the time spent by
a port in the listening and learning states.
forward delay timer value Current value of the forwarding delay timer, in seconds.
message age timer Status of the message age timer. This timer measures the age of the
received protocol information recorded for a port.
message age timer value Current value of the message age timer, in seconds.
topology change timer Status of the topology change timer. This timer determines the time
period during which configured BPDUs are transmitted with the topology
change flag set by this RoamAbout switch when it is the root bridge, after
detection of a topology change.
topology change timer value Current value of the topology change timer, in seconds.
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.
