instance
Congures MST instances and one or multiple VLANs mapped to the MST instance.
Syntax
instance instance-number {vlan vlan-range}
Parameters
• instance — Enter an MST instance value, from 0 to 63.
• vlan range — Enter a VLAN range value, from 1 to 4093.
Default Not congured
Command Mode MULTIPLE-SPANNING-TREE
Usage Information By default, all VLANs map to MST instance zero (0) unless you are using the vlan range command to map the
VLANs to a non-zero instance. The no version of this command removes the instance-related conguration.
Example
OS10(conf-mst)# instance 1 vlan 2-10
OS10(conf-mst)# instance 2 vlan 11-20
OS10(conf-mst)# instance 3 vlan 21-30
Supported Releases 10.2.0E or later
name
Assigns a name to the MST region.
Syntax
name region-name
Parameters region-name — Enter a name for an MST region. A maximum of 32 characters.
Default System MAC address
Command Mode MULTIPLE-SPANNING-TREE
Usage Information By default, the MST protocol assigns the system MAC address as the region name. Two MST devices within the
same region must share the same region name, including matching case.
Example
OS10(conf-mst)# name my-mst-region
Supported Releases 10.2.0E or later
revision
Congures a revision number for the MSTP conguration.
Syntax
revision number
Parameters number — Enter a revision number for the MSTP conguration, from 0 to 65535.
Default 0
Command Mode MULTIPLE-SPANNING-TREE
Usage Information To have a bridge in the same MST region as another, the default values for the revision number must match on all
Dell EMC hardware devices. If there are non-Dell EMC devices, ensure the revision number value matches on all
the devices. For more information, see Non-Dell Hardware.
