Services
This page covers the configuration of system management services SNMP and Ping
Watchdog.
Ping Watchdog
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.
Figure 21 – Ping Watchdog configuration
Enable Ping Watchdog: control will enable Ping Watchdog Tool.
IP Address To Ping: specify an IP address of the target host which will be monitored by
Ping Watchdog Tool.
Ping Interval: specify time interval (in seconds) between the ICMP “echo requests” are
sent by the Ping Watchdog Tool.
Startup Delay: specify initial time delay (in seconds) until first ICMP “echo requests” are
sent by the Ping Watchdog Tool. The value of Startup Delay should be at least 60
seconds as the network interface and wireless connection initialization takes
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.
SNMP Agent
SNMP Agent provides an interface for device monitoring using the Simple Network
Management Protocol (an application layer protocol that facilitates the exchange of
management information between network devices). SNMP Agent allows network
administrators to monitor network performance, find and solve network problems. For
the purpose of equipment identification, it is always a good idea to configure SNMP
agents with contact and location information:
