D-Link DWS-1008 CLI Manual 447
Field Description
message age
Age of the protocol information for a port and the value of the maximum age
parameter (shown in parenthesis) recorded by the switch.
designated_root MAC address of the root bridge.
designated cost Total path cost to reach the root bridge.
designated_bridge Bridge to which this switch forwards traffic away from the root bridge.
designated_port STP port through which this switch forwards traffic away from the root bridge.
top_change_ack
Value of the topology change acknowledgment flag in the next configured bridge
protocol data unit (BPDU) to be transmitted on the associated port. The flag is set
in reply to a topology change notification BPDU.
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 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 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
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.
bridge priority STP priority of this switch.
bridge MAC address MAC address of this switch.
bridge hello time
Value of the hello timer interval, in seconds, when this switch is the root or is
attempting to become the root.
