MSTP Configuration Commands 191Use the undo stp interface no-agreement-check command to disable port fasttransition.By default, port fast transition is disabled.Related command: stp no-agreement-check.n You can configure fast transition only on a root port or an alternate port.Example# Enable fast transition on GigabitEthernet1/1/1. system-viewSystem View: return to User View with Ctrl+Z.[SW8800]stp interface GigabitEthernet1/1/1 no-agreement-checkstp interfacepoint-to-pointSyntaxstp interface interface-list point-to-point { force-true | force-false | auto }undo stp interface interface-list point-to-pointViewSystem viewParameterinterface-list: Ethernet port list, containing multiple Ethernet ports and expressedas interface-list = { interface-type interface-number [ to interface-typeinterface-number ] }&<1-10>. For detail descriptions of interface-type andinterface-number parameters, refer to the corresponding descriptions in PortCommand Manual. &<1-10> means that the preceding parameters can beentered up to 10 times.force-true: Indicates the Ethernet port connected to a point-to-point link.force-false: Indicates the Ethernet port not connected to a point-to-point link.auto: Configures to automatically check if the link to the Ethernet port is apoint-to-point link.DescriptionUse the stp interface point-to-point command to configure a port (not) to beconnected to a point-to-point link in system view.Use the undo stp interface point-to-point command to restore the default stateof the link to the Ethernet port.By default, the parameter defaults to auto, that is, MSTP checks if the link to theEthernet port is a point-to-point link.The port not connected with the point-to-point link cannot transit fast.The master ports of the link aggregation and the ports operating in full-duplexmode are connected to the point-to-point link. You are recommended to keep thedefault settings and let MSTP detect the link state automatically.
