Use the data in the following table to help you understand the STG status display.
Variable | Value |
---|---|
Id | Indicates the STG ID. |
BridgeAddress | Indicates the MAC address used by this bridge. |
NumPorts | Indicates the number of ports controlled by this bridging entity. |
ProtocolSpecification | Indicates the version of spanning tree that is running. |
TimeSinceTopology Change |
Indicates the time, in hundredths of seconds, since the last topology change. |
TopChanges | Indicates the number of topology changes since the switch was reset. |
DesignatedRoot | Indicates the MAC address of the STP designated root. |
RootCost | Indicates the cost of the path to the root. |
RootPort | Indicates the port number of the port with the lowest-cost path from this bridge to the root bridge. |
MaxAge | Indicates the maximum age, in hundredths of a second, of STP information learned from any port in the network before the information is discarded. |
HelloTime | Indicates the amount of time, in hundredths of seconds, between Hello messages. |
HoldTime | Indicates the interval, in hundredths of seconds, during which no more than two Hello messages can be transmitted. |
ForwardDelay | Indicates the interval, in hundredths of seconds, during which the switch stays in Listening or Learning mode, before moving to Forwarding mode. This value is also used to age dynamic entries in the Forwarding Database. |
