Appendix IV- Services
This section provides more details on the system management services.
Ping WatchDog
The ping watchdog sets the device to continuously ping a user’s defined IP address (it can be the
internet gateway for example). If it is unable to ping under the user
’s defined constraints, the device will
automatically reboot. This option creates a "fail-proof" mechanism.
Ping watchdog is dedicated for continuous monitoring of a particular connection to a 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:
Using the
‘Control’ key will enable the ping watchdog tool.
IP Address to Ping:
Enter the target host IP address you wish to monitor.
Ping Interval:
Specify the time interval (in seconds) it takes between sending
the ICMP “echo
requests”.
Startup Delay:
Specify the initial time delay (in seconds) it takes the device from startup or
reboot to start sending the first ICMP
“echo requests”. Minimum value is 60 seconds.
Failure Count to Reboot:
Specify the number of ICMP “echo response” replies. If the
specified number of ICMP “echo response” packets is not continuously received, the ping
watchdog tool will reboot the device.
SNMP Agent
Simple Network Monitor Protocol (SNMP) is used in network management systems to monitor
network-attached devices for conditions that warrant administrative attention. The device contains an
SNMP agent that allows it to communicate to SNMP management applications for network
provisioning.
The 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). An SNMP agent allows network administrators to monitor network
performance to find and solve network problems. For equipment identification purposes, it is always a
good idea to configure SNMP agents with contact and location information.
Enable SNMP Agent:
Using the ‘Control’ key will enable the SNMP agent.
SNMP Community:
Specify the SNMP community string. It is required to confirm access to
MIB objects and functions as the embedded password. The device supports a read-only
community string that gives read access to authorized management stations and to all the
objects in the MIB except the community strings, but does not allow writing access for devices
that supports SNMP v1.
Contact:
Specify a contact (identity) in case an emergency situation arises.
Location:
Specify the physical location of the device.
