Use the read-only Status table to view the status of the Spanning Tree Protocol for each STG that is associated with the network.
To view the Status table:
| The Status table opens in the contents pane. |
The table below describes the fields in the Status table.
Device
IP address of the bridge.
NumPorts
Number of ports controlled by this bridging entity.
ProtocolSpecification
An indication of which version of the Spanning Tree Protocol (STP) is operating. The IEEE 802.1d implementations display ieee8021d.
TimeSinceTopologyChange
Time in hundredths of a second since the last time a topology change was detected by the bridge entity or STG.
TopChanges
The number of topology changes detected by this bridge since the management entity was last reset or initialized.
MaxAge
Maximum age of STP information learned from the network on any port before it is discarded, in units of hundredths of a second. This is the actual value that the bridge is currently using. The default value is 2000 (20 seconds).
HelloTime
Amount of time in hundredths of a second between transmission of configuration bridge protocol data units (BPDUs) by this device on any port when it is the root of the spanning tree. The default value is 200 (2 seconds).
HoldTime
Time interval in hundredths of a second during which no more than two configuration BPDUs are transmitted by this device. The default value is 100 (1 second).
ForwardDelay
Time interval in hundredths of a second that controls how fast a port changes its spanning state when moving toward the Forwarding state. This value determines how long the port stays in each of the Listening and Learning states, which precede the Forwarding state. This value is also used when a topology change is detected and is under way, to age all dynamic entries in the Forwarding Database. The default value is 1500 (15 seconds).
