If the defined number of replies is notreceived, the tool reboots the device.Enable Ping Watchdog Enables the Ping Watchdog tool.• IP Address To Ping Specify the IP address of the targethost which to be monitored by the Ping Watchdog tool.• Ping Interval Specify time interval (in seconds)between the ICMP “echo requests” are sent by the PingWatchdog Tool.
