Uplink Check

9.9.1

Overview

In AP mode, the AP connects to its upstream network using the LAN0 port. If a critical node between the LAN0
port and the upstream network fails, the AP as well as the wireless clients connected to the AP cannot access
the upstream network. If uplink check is enabled, the AP regularly pings specified hosts through the LAN0 port.
If all the hosts are not reachable, the AP stops its wireless service and wireless clients cannot find the SSIDs of
the AP. The client can reconnect to the AP only after the connection between the AP and the upstream
networks is recovered.
If the uplink of the AP with uplink check enabled is faulty, wireless clients can connect to the upstream
network through another nearby AP that works properly.
See the following topology (The LAN0 port serves as the uplink port).
