stp point-to-point

Use stp point-to-point to configure the link type of a port.

Use undo stp point-to-point to restore the default.

Syntax

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

undo stp point-to-point

Default

The default setting is auto, and the spanning tree device automatically detects whether a port connects to a point-to-point link.

Views

Layer 2 Ethernet interface view

Layer 2 aggregate interface view

Predefined user roles

network-admin

mdc-admin

Parameters

auto: Specifies automatic detection of the link type.

force-false: Specifies the non-point-to-point link type.

force-true: Specifies the point-to-point link type.

Usage guidelines

When connecting to a non-point-to-point link, a port is incapable of rapid state transition.

You can configure the link type as point-to-point for a Layer 2 aggregate interface or a port that operates in full duplex mode. As a best practice, use the default setting to let the device automatically detect the port link type.

In MSTP or PVST mode, the stp point-to-point force-false or stp point-to-point force-true command configured on a port takes effect on all MSTIs or VLANs.

Before you set the link type of a port to point-to-point, make sure the port is connected to a point-to-point link. Otherwise, a temporary loop might occur.

If this command is configured in Layer 2 Ethernet interface view, it takes effect only on that interface.

If this command is configured in Layer 2 aggregate interface view, it takes effect only on the aggregate interface.

If this command is configured on a member port in an aggregation group, it takes effect only after the port leaves the aggregation group.

Examples

# Configure the link type of Ten-GigabitEthernet 1/0/1 as point-to-point.

<Sysname> system-view
[Sysname] interface ten-gigabitethernet 1/0/1
[Sysname-Ten-GigabitEthernet1/0/1] stp point-to-point force-true
