SPANNING TREE MST INSTANCE RESTRICTED

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.
