SPANNING TREE MST INSTANCE

spanning-tree mst instance

Overview Use this command to assign a Multiple Spanning Tree instance (MSTI) to a switch
port or channel group.
Note that ports are automatically configured to send and receive spanning-tree
information for the associated MSTI when VLANs are assigned to MSTIs using the
instance vlan (MSTP)
Use the no variant of this command in Interface Configuration mode to remove the
MSTI from the specified switch port or channel group.
spanning-tree mst instance <instance-id>
Syntax
no spanning-tree mst instance <instance-id>
Default A port automatically becomes a member of an MSTI when it is assigned to a VLAN.
Mode Interface Configuration mode for a switch port or channel group.
Usage You can disable automatic configuration of member ports of a VLAN to an
associated MSTI by using a no spanning-tree mst instance command to remove
the member port from the MSTI. Use the spanning-tree mst instance command
to add a VLAN member port back to the MSTI.
