SPANNING-TREE MST INSTANCE

Syntax

spanning-tree mst

instance

<1-15>

Parameters

instance

Specifies an instance ID. The range is from 1 to 15.

Mode

Interface Configuration mode

Description

Use this command to associate a Multiple Spanning Tree instance (MSTI)
with a port. Before you assign an instance ID to a port, you must create an
instance. To create an instance, use the INSTANCE MSTI-ID VLAN
command. See “INSTANCE MSTI-ID VLAN” on page 857.

Ports are automatically configured to send and receive spanning-tree
information for the associated MSTI when you assign a VLAN to the MSTI
using the INSTANCE MST-ID VLAN command. For information about this
command, see “INSTANCE MSTI-ID VLAN” on page 857.

To remove the association between an MST instance and a port, use the
NO SPANNING-TREE MST INSTANCE command. In addition, to disable
the automatic configuration of member ports of a VLAN to an associated
MSTI, use the NO SPANNING-TREE MST INSTANCE command to
remove the member port from the MSTI.

Confirmation Command

“SHOW SPANNING-TREE” on page 861

Example

In the following example, port 2 is associated with instance 12:

awplus> enable
awplus# configure terminal
awplus(config)# interface port1.0.2
awplus(config-if)# spanning-tree mst instance 12
