14.1.3 instance vlan
Command:
instance <instance-id> vlan <vlan-list>
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 64; in the command
“no instance <instance-id> [vlan <vlan-list>]”, <instance-id> sets the instance number. The valid
number is from 0 to 64. <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 1~4094 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
64 MSTIs (except for CISTs). CIST can be treated as MSTI 0. All the other instances are considered
as instance 1 to 64.
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
14.1.4 name
Command:
name <name>
no name
Function:
In MSTP region mode, set MSTP region name; the “no name” command restores the default
