This example shows the current CIST configuration (MSTP instance 0).
The following table describes the labels in this screen.
TransmissionLimit
This field displays the maximum number of BPDUs that can be transmitted
in the interval specified by BridgeHelloTime.
ForceVersion
This field indicates whether BPDUs are RSTP (a value less than 3) or
MSTP (a value greater than or equal to 3).
MST Configuration ID
Format Selector
This field displays zero, which indicates the use of the fields below.
Configuration Name
This field displays the configuration name for this MST region.
Revision Number
This field displays the revision number for this MST region.
Configuration Digest
A configuration digest is generated from the VLAN-MSTI mapping
information.
This field displays the 16-octet signature that is included in an MSTP
BPDU. This field displays the digest when MSTP is activated on the
system.
msti
This field displays the MSTI ID.
vlans mapped
This field displays which VLANs are mapped to an MSTI.
