Compex Systems 802.11N Manual De Usuario

This section provides more details on the system management services.   

The ping watchdog sets the device 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 device 

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: control will enable Ping Watchdog Tool.   

IP Address To Ping: enter the target host IP address to monitor.   

Ping Interval: specify time interval (in seconds) between to send the ICMP “echo requests”.       

Startup Delay: specify initial time delay (in seconds) from device startup or reboot to start 

sending 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 received continuously, the Ping Watchdog Tool 

will reboot the device.   

Simple Network Monitor Protocol (SNMP) is used in network management systems to monitor 

network-attached devices for conditions that warrant administrative attention. Device contains an 

SNMP agent which allows it to communicate to SNMP manage applications for network 

provisioning.  

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:   

 

Enable SNMP Agent: control will enable SNMP Agent.   

SNMP Community: specify SNMP community string. It is required to authenticate access to 

MIB objects and functions as embedded password. The device supports a Read-only community 

string that gives read access to authorized management stations to all the objects in the MIB 

except the community strings, but does not allow write access for device that supports SNMP v1.   

Contact: specify the identity or contact in case an emergency situation arise.   

Location: specify the physical location of the device.
