Ping WatchDog
The ping watchdog sets the AirOS Device 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, the AirOS device will automatically reboot. This option creates
a kind of "fail-proof" mechanism.
Ping Watchdog is dedicated for continuous monitoring of the particular connection to
remote host using the Ping tool. The Ping 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 device.
Enable Ping Watchdog: control will enable Ping Watchdog Tool.
IP Address To Ping: specify an IP address of the target host which will be monitored by
Ping Watchdog Tool.
Ping Interval: specify time interval (in seconds) between the ICMP “echo requests” are
sent by the Ping Watchdog Tool.
Startup Delay: specify initial time delay (in seconds) until first ICMP “echo requests”
are sent by the Ping Watchdog Tool. The value of Startup Delay should be at least 60
seconds as the network interface and wireless connection initialization takes
considerable amount of time if the device is rebooted.
