The following table outlines the parameters of the MSTI Bridges tab.
MSTP MSTI Bridges tab parameters
Variable | Value |
---|---|
Instance | Spanning Tree Instance to which the information belongs. |
RegionalRoot | Indicates the MSTI Regional Root Identifier value for the Instance. This value is used as the MSTI Regional Root Identifier parameter in all Configuration Bridge PDUs originated by this node. |
Priority | The writable portion of the MSTI Bridge Identifier comprising the first two octets. The values that are set for Bridge Priority must be in steps of 4096. |
RootCost | The cost of the path to the MSTI Regional Root as seen by this bridge. |
RootPort | The number of the port which offers the lowest path cost from this bridge to the MSTI Region Root Bridge. |
Enabled | Used to control whether the bridge instance is enabled or disabled. |
TimeSinceTopology Change |
The time (measured in hundredths of a second) since the TcWhile Timer for any port in this Bridge was non-zero for this Spanning Tree instance. |
TopChanges | The number of times that at least one non-zero TcWhile Timer occurred on this Bridge for this Spanning Tree instance. |
NewRootCount | The number of times this Bridge has detected a Root Bridge change for this Spanning Tree instance. A Trap is generated on the occurrence of this event. |
InstanceUpCount | The number of times a new Spanning Tree instance was created. A Trap is generated on the occurrence of this event. |
InstanceDownCount | The number of times a Spanning Tree instance was deleted. A Trap is generated on the occurrence of this event. |
