stp point-to-point (VSI-LDP-PW view)

Function

The stp point-to-point command sets the link type of a port.

The undo stp point-to-point command restores the default link type.

By default, the link type of the ports on the device is auto. That is, the spanning tree protocol detects whether a port is connected to a point to point (P2P) link.

Format

stp point-to-point { auto | force-false | force-true }

undo stp point-to-point

Parameters

Parameter	Description	Value
auto	Indicates that the spanning tree protocol detects automatically whether the port is connected to a P2P link.	-
force-false	Indicates that the link type is non-P2P.	-
force-true	Indicates that the link type is P2P.	-

Parameter

Description

Value

auto

Usage Guidelines

Usage Scenario

On a Layer 2 network running STP, if a port of a device is connected to a non-P2P link, the port cannot perform fast status transition.

If a port works in full-duplex mode, the port is connected to a P2P link, and force-true can be set in the stp point-to-point command.

If a port works in half-duplex mode, run the stp point-to-point force-true command to forcibly set the type of the link to which the port is connected to P2P, implementing rapid network convergence.

Configuration Impact

The stp point-to-point command configuration on a port takes effect in all spanning tree instances where the port resides.

Example

# Set the link type of pw1 to P2P.
