2-716Cisco Catalyst Blade Switch 3120 for HP Command ReferenceOL-12248-03Chapter 2 Cisco Catalyst Blade Switch 3120 for HP Cisco IOS Commandsspanning-tree link-typespanning-tree link-typeUse the spanning-tree link-type interface configuration command on the switch stack or on astandalone switch to override the default link-type setting, which is determined by the duplex mode ofthe interface, and to enable rapid spanning-tree transitions to the forwarding state. Use the no form ofthis command to return to the default setting.spanning-tree link-type {point-to-point | shared}no spanning-tree link-typeSyntax DescriptionDefaults The switch derives the link type of an interface from the duplex mode. A full-duplex interface isconsidered a point-to-point link, and a half-duplex interface is considered a shared link.Command Modes Interface configurationCommand HistoryUsage Guidelines You can override the default setting of the link type by using the spanning-tree link-type command.For example, a half-duplex link can be physically connected point-to-point to a single interface on aremote switch running the Multiple Spanning Tree Protocol (MSTP) or the rapid per-VLANspanning-tree plus (rapid-PVST+) protocol and be enabled for rapid transitions.Examples This example shows how to specify the link type as shared (regardless of the duplex setting) and toprevent rapid transitions to the forwarding state:Switch(config-if)# spanning-tree link-type sharedYou can verify your setting by entering the show spanning-tree mst interface interface-id or the showspanning-tree interface interface-id privileged EXEC command.point-to-point Specify that the link type of an interface is point-to-point.shared Specify that the link type of an interface is shared.Release Modification12.2(40)EX1 This command was introduced.
