Function

The max-rssi-threshold command sets the maximum RSSI threshold of a Mesh link in a Mesh handover profile.

The undo max-rssi-threshold command restores the default maximum RSSI threshold of a Mesh link in a Mesh handover profile.

By default, the maximum RSSI threshold of a Mesh link is -20 dBm in a Mesh handover profile.

Usage Guidelines

Usage Scenario

During a vehicle-ground fast link handover, the vehicle-mounted AP selects the candidate link of the best quality as the active link from the candidate area (the RSSI range of a candidate area is from the minimum RSSI threshold to the maximum RSSI threshold of the Mesh link). An emergency handover is triggered when the RSSI of the current active link is out of the RSSI range of the candidate area (falls below the minimum RSSI threshold of a Mesh link or exceeds the maximum RSSI threshold of a Mesh link).

In actual scenarios, set proper minimum and maximum RSSIs of a Mesh link according to network deployment. Improper values result in frequent emergency handovers or untimely handovers, degrading vehicle-ground fast link handover performance.

Example

# Set the maximum RSSI threshold of a Mesh link to -15 dBm in the Mesh handover profile huawei.
