The instance parameter defines the number for the instance of MSTP that you are deleting.
The vlan parameter identifies one or more VLANs or a range of VLANs to the instance defined in
this command.
The vlan-group parameter identifies one or more VLAN groups to the instance defined in this
command.
Viewing the MSTP configuration digest
The MSTP Configuration Digest indicates the occurrence of an MSTP reconvergence. The
Configuration Digest is recalculated whenever an MSTP reconvergence occurs. To view the
Configuration Digest, use the show mstp config command. The following shows an example
output.
Syntax: show mstp config
Configuring additional MSTP parameters
To configure a switch for MSTP, you could configure the name and the revision on each switch that
is being configured for MSTP. You must then create an MSTP Instance and assign an ID. VLANs are
then assigned to MSTP instances. These instances must be configured on all switches that
interoperate with the same VLAN assignments. Port cost, priority and global parameters can then
be configured for individual ports and instances. In addition, operational edge ports and
point-to-point links can be created and MSTP can be disabled on individual ports.
Each of the commands used to configure and operate MSTP are described in the following:
“Setting the MSTP name”
“Setting the MSTP revision number”
“Configuring an MSTP instance”
“Configuring bridge priority for an MSTP instance”
“Setting the MSTP global parameters”
“Setting ports to be operational edge ports”
“Setting automatic operational edge ports”
“Setting point-to-point link”
“Disabling MSTP on a port”
