Chapter 7: Services Tab
The Services tab configures system management services:
Ping Watchdog , SNMP Agent , Web Server , SSH Server , Telnet
Server , NTP Client , Dynamic DNS , System Log , and Device
Discovery .
Ping Watchdog
Ping Watchdog sets the airFiber AF-24 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, then the airFiber AF-24 will
automatically reboot. This option creates a kind of
“fail-proof” mechanism.
Ping Watchdog is dedicated to continuous monitoring of
the specific connection to the remote host using the Ping
tool. The Ping tool 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 airFiber AF-24.
Ping Watchdog Enables use of Ping Watchdog .
• IP Address To Ping Specify the IP address of the target
host to be monitored by Ping Watchdog .
•
Ping Interval
Specify the time interval (in seconds)
between the ICMP echo requests that are sent by Ping
Watchdog . The default value is 300 seconds.
• Startup Delay Specify the initial time delay (in seconds)
until the first ICMP echo requests are sent by Ping
Watchdog . The default value is 300 seconds.
The Startup Delay value should be at least 60 seconds
as the network interface and wireless connection
initialization takes a considerable amount of time if the
airFiber AF-24 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,
Ping Watchdog will reboot the airFiber AF-24. The
default value is 3 .
• Save Support Info This generates a support
information file.
SNMP Agent
Simple Network Monitor Protocol (SNMP) is an
application layer protocol that facilitates the exchange
of management information between network
devices. Network administrators use SNMP to monitor
network-attached devices for issues that warrant
attention.
