failover-internet
Enables uplink switchover based on
the availability of the Internet. When
enabled, the AP continuously sends
ICMP packets to some well- known
Internet servers. If the request is
timed out due to a bad uplink connec-
tion or uplink interface failure, and the
public Internet is not reachable from
the current uplink, the AP switches to
a different connection.

Allows you toconfigure theIP address
to which theICMP packets are sent in
the event of Internet failure.If the out-
of-service feature is enabled for the
Internet down event in the SSID
andthe Internet is down, the ICMP
packets are sent to the configured IP
address to verify if the Intenet is
reachable from current uplink. Byde-
fault, the master APs send the ICMP
packets to 8.8.8.8 IP address toverify
if the Internet is reachable.
