no instance <instance-id> [vlan <vlan-list>]
Function: In MSTP region mode, create the instance and set the mappings between
VLANs and instances; The command “no instance <instance-id> [vlan <vlan-list>]
removes the specified instance and the specified mappings between the VLANs and
instances.
Parameter: Normally, <instance-id> sets the instance number. The valid range is from 0
to 48.; In the command “no instance <instance-id> [vlan <vlan-list>]”, <instance-id>
sets the instance number. The valid number is from 1 to 48. <vlan-list> sets consecutive
or non-consecutive VLAN numbers. “-” refers to consecutive numbers, and “;” refers to
non-consecutive numbers.
Command mode: MSTP Region Mode
Default: Before creating any Instances, there is only the instance 0, and VLAN 1~5094 all
belong to the instance 0.
Usage Guide: This command sets the mappings between VLANs and instances. Only if
all the mapping relationships and other attributes are same, the switches are considered
in the same MSTP region. Before setting any instances, all the VLANs belong to the
instance 0. MSTP can support maximum 48 MSTIs (except for CISTs). CIST can be
treated as MSTI 0. All the other instances are considered as instance 1 to 48.
Example: Map VLAN1-10 and VLAN 100-110 to Instance 1.
Switch(Config)#spanning-tree mst configuration
Switch(Config-Mstp-Region)#instance 1 vlan 1-10;100-110
6.2.2.4 name
Command: name <name>
no name
Function: In MSTP region mode, set MSTP region name; The “no name” command
restores the default setting.
Parameter: <name> is the MSTP region name. The length of the name should less than
32 characters.
Command mode: MSTP Region Mode
Default: Default MSTP region name is the MAC address of this bridge.
Usage Guide: This command is to set MSTP region name. The bridges with same MSTP
region name and same other attributes are considered in the same MSTP region.
Example: Set MSTP region name to mstp-test
Switch(Config)#spanning-tree mst configuration
Switch(Config-Mstp-Region)#name mstp-test
