2.23.20.7.5 Broken-Link-Detection

When an access point is not connected to the cabled LAN, it is normally unable to fulfill its primary task, namely the authorization of WLAN clients for access to the LAN. The broken-link detection function allows a device's WLAN to be disabled if the connection to the LAN should fail. Clients associated with that access point are then able to login to a different one (even if it has a weaker signal).

Until LCOS version 7.80, broken-link detection always applied to LAN-1, even if the device was equipped with multiple LAN interfaces. Furthermore, deactivation affected all of the WLAN modules in the device. With LCOS version 7.82, broken-link detection could be bound to a specific LAN interface.

This function allows the WLAN modules in a device to be disabled if the allocated LAN interface has no connection to the LAN.

Note: The interface names LAN-1 to LAN-n represent the logical LAN interfaces. To make use of this function, the physical Ethernet ports on the device must be set with the corresponding values LAN-1 to LAN-n.

Note: Broken-link detection can also be used for WLAN devices operating in WLAN client mode. With broken-link detection activated, the WLAN modules of a WLAN client are only activated when a connection exists between the relevant LAN interfaces and the cabled LAN.

No: Broken-link detection is disabled.
LAN-1 to LAN-n (depending on the LAN interfaces available in the device): All of the WLAN modules in the device will be deactivated if the LAN interface set here should lose its connection to the cabled LAN.
