stp interface
point-to-point
Syntax
stp interface interface-list point-to-point { force-true | force-false | auto }
undo stp interface interface-list point-to-point
View
System view
Parameter
interface-list : Ethernet port list, containing multiple Ethernet ports and expressed
as interface-list = { interface-type interface-number [ to interface-type
interface-number ] }&<1-10>. For detail descriptions of interface-type and
i nterface-number parameters, refer to the corresponding descriptions in Port
Command Manual . &<1-10> means that the preceding parameters can be
entered 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 a
point-to-point link.
Description
Use the stp interface point-to-point command to configure a port (not) to be
connected to a point-to-point link in system view.
Use the undo stp interface point-to-point command to restore the default state
of the link to the Ethernet port.
By default, the parameter defaults to auto, that is, MSTP checks if the link to the
Ethernet 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-duplex
mode are connected to the point-to-point link. You are recommended to keep the
default settings and let MSTP detect the link state automatically.
