Chapter 8: Services Tab
The Services tab covers the configuration of system
management services including: Ping Watchdog,
SNMP Agent, Web Server, SSH Server, Telnet Server,
NTP Client, Dynamic DNS and System Log.
Ping Watchdog
Ping Watchdog sets the AirRouter HP 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 AirRouter HP 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
Enables the Ping Watchdog tool.
•
IP Address To Ping
Specify the IP address of the target
host 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 Ping
Watchdog Tool. The default value is 300 seconds.
•
Startup Delay
Specify initial time delay (in seconds)
until the first ICMP echo requests are sent by the Ping
Watchdog tool. The default value is 300 seconds.
The value of 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. The default
value is 3.
