Configuring MSTI bridges for MSTP
Perform this procedure to configure multiple spanning tree instance (MSTI) bridges for MSTP.
Procedure
-
Click the MSTI Bridges
tab.
Note
The systems generates MSTI bridge instances after you create a VLAN in MSTP mode.
MSTI Bridges field descriptions
Use the data in the following table to use the MSTI Bridges tab.
|
Name |
Description |
|---|---|
|
Instance |
Specifies the spanning tree instance to which this information belongs. |
|
RegionalRoot |
Specifies 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 |
Specifies the writable portion of the MSTI bridge identifier comprising the first two octets. The values that are configured for bridge priority must be in steps of 4096. The default is 32768. |
|
RootCost |
Specifies the cost of the path to the MSTI regional root as seen by this bridge. |
|
RootPort |
Specifies the port number of the port that offers the lowest path cost from this bridge to the MSTI region root bridge. |
|
TimeSinceTopologyChange |
Specifies the time (in hundredths of a second) since the TcWhile Timer for any port in this bridge was nonzero for this spanning tree instance. |
|
TopChanges |
Specifies the number of times that there was at least one nonzero TcWhile Timer on this bridge for this spanning tree instance. |
|
NewRootCount |
Specifies the number of times this bridge detects a root bridge change for this spanning tree instance. A trap is generated on the occurrence of this event. |
|
InstanceUpCount |
Specifies the number of times a new spanning tree instance is created. A trap is generated on the occurrence of this event. |
|
InstanceDownCount |
Specifies the number of times a spanning tree instance is deleted. A trap is generated on the occurrence of this event. |
