Ping Watchdog
Ping Watchdog sets the AF-5X to continuously ping a
user-defined IP address (it can be the Internet gateway,
for example). If it is unable to ping under the user-defined
constraints, then the AF-5X will automatically reboot. This
option creates a kind of “fail-proof” mechanism.
Ping Watchdog is dedicated to continuous monitoring of
the specific connection to the remote host using the Ping
tool. The Ping tool works by sending ICMP echo request
packets to the target host and listening for ICMP echo
response replies. If the defined number of replies is not
received, the tool reboots the AF-5X.
Ping Watchdog Enables use of Ping Watchdog.
• IP Address To Ping Specify the IP address of the target
