Instance Vlan (Mstp) - Allied Telesis SwitchBlade x908 Series Software Reference Manual

Spanning Tree Commands

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 instance vlan 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>}
Parameter
<msti-id>

MSTI. If you use the no 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 version 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
