Connectivity Guide

Parameters None
Default Not congured.
Usage Information The no version of this command re-enables STP and applies the currently congured spanning-tree settings.
Command Mode
CONFIGURATION
INTERFACE
Example
OS10(config)# interface ethernet 1/1/4
OS10(config-if-eth1/1/4)# spanning-tree disable
Supported Releases 10.3.0E or later
spanning-tree guard
Enables or disables loop guard or root guard on an interface.
Syntax
spanning-tree guard {loop | root | none}
Parameters
• loop — Enables loop guard on an interface.
• root — Enables root guard on an interface.
• none — Sets the guard mode to none.
Default Not congured
Usage Information Root guard and loop guard congurations are mutually exclusive. Conguring one overwrites the other from the
active conguration.
Command Mode INTERFACE
Example
OS10(conf-if-eth1/1/4)# spanning-tree guard root
Supported Releases 10.2.0E or later
spanning-tree link-type
Sets the spanning-tree link type for faster convergence.
Syntax
spanning-tree link-type {auto | point-to-point | shared}
Parameters
• auto — Enter the keyword to sets the link type based on the duplex setting of the interface.
• point-to-point—Species that the interface is a point-to-point or full-duplex link.
• shared—Species that the interface is a half-duplex medium.
Default Auto
Command Mode INTERFACE
Usage Information
As specied in IEEE 802.1w, OS10 assumes a port that runs in full duplex mode as a point-to-point link. A point-to-
point link transitions to forwarding state faster. By default, OS10 derives the link type of a port from the duplex
mode. You can override the duplex mode using the spanning-tree link-type command.
