Example

spanning-tree link-type

This command configures the link type for Rapid Spanning Tree and Multiple
Spanning Tree. Use the no form to restore the default.

Syntax

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.

Default Setting

auto

Command Mode

Interface Configuration (Ethernet, Port Channel)

Command Usage

• 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 link.

• 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.

Example

spanning-tree loopback-detection

This command enables the detection and response to Spanning Tree loopback
BPDU packets on the port. Use the no form to disable this feature.
