spanning-tree mst instance restricted-role
Overview Use this command in Interface Configuration mode for a switch port interface only
to enable the restricted role for an MSTI (Multiple Spanning Tree Instance) on a
switch port. Configuring the restricted role for an MSTI on a switch port prevents
the switch port from becoming the root port in a spanning tree topology.
Use the no variant of this command to disable the restricted role for an MSTI on a
switch port. Removing the restricted role for an MSTI on a switch port allows the
switch port to become the root port in a spanning tree topology.
Syntax spanning-tree mst instance < instance-id > restricted-role
no spanning-tree mst instance < instance-id > restricted-role
Default The restricted role for an MSTI instance on a switch port is disabled by default.
Mode Interface Configuration mode for a switch port interface only.
Usage The root port is the port providing the best path from the bridge to the root bridge.
Use this command to disable a port from becoming a root port. Use the
no variant
of this command to enable a port to become a root port. See the STP Feature
Overview and Configuration Guide for root port information.
Examples To prevent a switch port from becoming the root port, use the commands:
awplus# configure terminal
awplus(config)# interface port1.0.2
awplus(config-if)# spanning-tree mst instance 3 restricted-role
To stop preventing the switch port from becoming the root port, use the
commands:
awplus# configure terminal
awplus(config)# interface port1.0.2
awplus(config-if)# no spanning-tree mst instance 3
