link-probe-interval

Function

The link-probe-interval command sets a Mesh link probe interval in a Mesh handover profile.

The undo link-probe-interval command restores the default Mesh link probe interval in a Mesh handover profile.

By default, the Mesh link probe interval is 100 ms in a Mesh handover profile.

Format

Parameters

Parameter	Description	Value
value	Specifies the interval for detecting Mesh links.	The value is an integer that ranges from 50 to 6000, in milliseconds. The default value is 100.

Usage Guidelines

In vehicle-ground communication scenarios, a trackside AP periodically sends unicast probe frames to detect RSSIs of Mesh links and executes the handover algorithm based on the detection result. A larger interval delays link handovers, interrupting vehicle-ground communications. A smaller interval increases air port costs and burden. Therefore, you need to configure a proper interval for detecting Mesh links according to train operating conditions.

Example

# Set the Mesh link probe interval to 150 ms in Mesh handover profile huawei.
