instance vlan (MSTP)
Use this command to create an MST Instance (MSTI), and associate the specified VLANs
with it. An MSTI is a spanning tree instance that exists within an MST region (MSTR). An
MSTR can contain up to 15 MSTIs.
When a VLAN is associated with an MSTI the member ports of the VLAN are automatically
configured to send and receive spanning-tree information for the associated MSTI. You
can disable this automatic configuration of member ports of the VLAN to the associated
MSTI by using a no spanning-tree mst instance command to remove the member port
from the MSTI.
Use the instance vlan command for MSTP only.
Use the no variant of this command to remove the specified VLANs from the MSTI.
Syntax
instance <msti-id> vlan {<vid>|<vid-list>}
no instance <msti-id> vlan {<vid>|<vid-list>}
Mode
MST Configuration
Usage
The VLANs must be created before being associated with an MST instance (MSTI). If the
VLAN range is not specified, the MSTI will not be created.
This command removes the specified VLANs from the CIST and adds them to the specified
MSTI. If you use the no variant of this command to remove the VLAN from the MSTI, it
returns it to the CIST. To move a VLAN from one MSTI to another, you must first use the no
variant of this command to return it to the CIST.
Ports in these VLANs will remain in the control of the CIST until you associate the ports
with the MSTI using the
command.
