MST commands
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 a 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

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.
