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.
