19.1.3 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.
