This command configures the link type for Rapid Spanning Tree and

Multiple Spanning Tree. Use the no form to restore the default.

spanning-tree link-type {auto | point-to-point | shared}

no spanning-tree link-type

auto - Automatically derived from the duplex mode setting.

point-to-point - Point-to-point link.

shared - Shared medium.

Interface Configuration (Ethernet, Port Channel)

Specify a point-to-point link if the interface can only be connected to

exactly one other bridge, or a shared link if it can be connected to two

or more bridges.

When automatic detection is selected, the switch derives the link type

from the duplex mode. A full-duplex interface is considered a point-to-

point link, while a half-duplex interface is assumed to be on a shared

RSTP only works on point-to-point links between two bridges. If you

designate a port as a shared link, RSTP is forbidden. Since MSTP is an

extension of RSTP, this same restriction applies.

Console(config)#interface ethernet 1/5

Console(config-if)#spanning-tree link-type point-to-point

This command enables the detection and response to Spanning Tree

loopback BPDU packets on the port. Use the no form to disable this
