Ping Watch dog & Ping Test

1. Ping Watch Dog


Minimum Software version : 15.1 


Ping Watch dog helps administrator to automatically reboot the AP/SM when ever there is a network issue .

 This avoids the need of power on reset of radios. By default this feature is disabled, Feature can be enabled from Configuration->Ping Watch dog Tab or using SNMP OID's. Admin need to configure the device IP Address (Say for example default gateway IP Address) which is reachable from radio, ping interval and Ping Failure Count to Reboot in Ping Watchdog configuration


Configuration from web GUI



SNMP OID Details:

Name OID Type Access MIB Module Description
pingWdogEnable . INTEGER read-write WHISP-BOX-MIBV2-MIB enable(1) or disable(0) ping watchdog.
pingWdogIP . IPADDRESS read-write WHISP-BOX-MIBV2-MIB IPv4 address to ping in dotted decimal notation
pingWdogInterval . INTEGER read-write WHISP-BOX-MIBV2-MIB Intervals in seconds at which ping should be initiated
pingWdogRbtCnt . INTEGER read-write WHISP-BOX-MIBV2-MIB Ping Failures count at which reboot should be initiated


Ping Watchdog Explained


Say Configuration parameters are

1. IP Address To Ping :
2. Ping Interval : 300 sec
3. Ping Failure Count To Reboot : 3

  • What this means is every 300 sec radio will try to ping the IP address, IF the IP address is reachable radio will never reboot.

  • Ping Failure Count To Reboot is specified as 3, any 3 consecutive  ping loss will trigger a reboot of radio at the 4th interval. i.e (300 Sec * 3 + 300 Sec).

  • Following equation will give reboot interval.

        Reboot interval = Configured interval * (Reboot Count + 1)


If the Ping watchdog is enabled  and if the IP address configured is not reachable then then on reboot the following information will be available  in event logs

2. PING Test 


Minimum Software version : 15.1 

With ping test ( Tools->PING Test) , now admin can ping any IPV4 address/Fully Qualified Domain Name.

Radio will internally issue 3 ping requests to the target IP/FQDN and display the results ( auto update of results will happen only if web page auto update is turned on )
