Configuring Watchdog settings
The Watchdog settings configure the router to transmit controlled ping packets to 2 specified IP addresses. If the router does not
receive responses to the pings, the router will reboot.
To configure the ping watchdog:
1.
In the First destination address field, enter a website address or IP address to which the router should send the first round
of ping requests.
2.
In the Second destination address field, enter a website address or IP address to which the router should send the second
round of ping requests.
3.
In the Periodic Ping timer field, enter an integer between 300 and 65535 for the number of seconds the router should wait
between ping attempts. Setting this to 0 disables the ping watchdog function.
4.
In the Periodic Ping accelerated timer field, enter an integer between 60 and 65535 for the number of seconds the router
should wait between accelerated ping attempts, i.e. pings to the second destination address. Setting this to 0 disables the
ping watchdog function
5.
In the Fail count field, enter an integer between 1 and 65535 for the number of times an accelerated ping should fail before
the router reboots. Setting this to 0 disables the ping watchdog function.
Disabling the Watchdog function
To disable the Watchdog reset function, set Fail count to 0.
Note: The traffic generated by the Watchdog feature is usually counted as chargeable data usage. Please keep this in mind
when selecting how often to ping.
Configuring a periodic reboot
The router can be configured to automatically reboot after a period of time specified in minutes. While this is not necessary, it does
ensure that in the case of remote installations, the router will reboot if some anomaly occurs.
1.
In the Force reboot every field, enter the time in minutes between forced reboots. The default value is 0 which disables the
Periodic reboot function. The minimum period between reboots is 5 minutes while the maximum value is 65535 minutes.
2.
If you have configured a forced reboot time, you can use the Randomize reboot time drop down list to select a random
reboot timer. Randomizing the reboot time is useful for preventing a large number of devices from rebooting
simultaneously and flooding the network with connection attempts. When configured, the router waits for the configured
Force reboot every time and then randomly selects a time that is less than or equal to the Randomize reboot time setting.
After that randomly selected time has elapsed, the router reboots.
3.
Click the Save button to save the settings.
Note: The randomize reboot time is not persistent across reboots; each time the router is due to reboot, it randomly selects
a time less than or equal to the Randomize reboot time.
