Uplink Detection

8.6.1

Overview

In AP mode, the AP connects to its upstream network using the PoE LAN port. If a critical node
between the PoE LAN 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 detection is enabled, the AP
regularly pings specified hosts through the PoE LAN 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 detection enabled is faulty, wireless clients can connect to the
upstream network through another nearby AP that works properly.
See the following topology (The PoE LAN port serves as the uplink port).
