N-Tron 702M12-W user manual Service, Ping WatchDog

Service Page

This page covers the configuration of the following system management services; Ping Watchdog, SNMP, NTP, Web Server, Telnet Server, SSH Server and System Log.

Ping WatchDog

The ping watchdog sets the N-TRON 702-W Device to continuously ping a user defined IP address (for example the Internet gateway). If it is unable to ping under the user defined constraints, the N-TRON 702- W device will automatically reboot. This option decreases the likelihood of failure using a relative "fail- proof" mechanism.

Ping Watchdog is dedicated for continuous monitoring of a particular connection to a remote host using the Ping tool. 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 the Ping Watchdog Tool.

IP Address To Ping: specify an IP address of the target host which will be monitored by the Ping Watchdog Tool.

Ping Interval: specify a time interval (in seconds) between the ICMP “echo requests” sent by the Ping Watchdog Tool.

Startup Delay: specify initial time delay (in seconds) until the first ICMP “echo requests” are sent by the Ping Watchdog Tool. The value of the Startup Delay should be at least 60 seconds as the network interface and wireless connection initialization takes a considerable amount of time if the device is rebooted.

Failure Count To Reboot: specify the number of ICMP “echo response” replies. If the specified number of ICMP “echo response” packets is not received continuously, the Ping Watchdog Tool will reboot the device.
