Status group

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:

In the navigation pane, select Status.
The Status table opens in the contents pane.

The following table describes the Status table fields.


Field Description 
Device
The IP address of the bridge.
NumPorts
The number of ports controlled by this bridging entity.
ProtocolSpecification
An indication of what version of the Spanning Tree Protocol (STP) is operating. The IEEE 802.1d implementations will return ieee8021d.
TimeSinceTopologyChange
The time in hundredths of a second since the last time a topology change was detected by the bridge entity or STG.
TopChanges
A topology change trap is sent by a bridge when any of its configured ports transitions from the Learning state to the Forwarding state, or from the Forwarding state to the Blocking state. The trap is not sent if a new root trap is sent for the same transition. Implementation of this trap is optional.
MaxAge
The 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
The amount of time in hundredths of a second between transmission of config 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
The 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
The time interval in hundredths of a second that controls how fast a port changes its spanning state when moving toward the Forwarding state. The 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).
