As with every other technology, remote monitoring systems also follow organized paradigms of operation.

The fields that you may need for remote monitoring services are described in the article:Read password

This is the read-only password used for SNMP I support. It is the SNMP password needed to read the MIB variables. The string public is the common password used by most SNMP monitors.Read/write passwordThis is the read/write password used for SNMP support. It is the SNMP password needed to write the MIB variables. The string should be set to a value known only by you. The factory default value for this variable is the string public and should be changed to a string known only to you.System contactThis defines the value of the MIB variable,The Many and Varied Fields of Remote Monitoring Technology Articles sysContact, for system contact. This could be the name of a person or a telephone number.System nameThis defines the value of the MIB variable, sysName, for system name. This is a description of the system.System locationThis defines the value of the MIB variable, sysLocation, for system location. This is a description of the system.Trap host IP addressThis is the address of the host to which the remote server’s trap messages are sent. The host must be set to run an SNMP trap logger that can log these traps. Typically, this is the IP address of the SNMP manager.Trap host passwordOnly hosts that have this password set for trap messages can receive this trap message. The string public is the common password used to receive SNMP trap receivers.Enable SNMP cold/warm start trapWhen enabled, SNMP trap messages are sent for cold and warm boot of the SNMP agent in the monitoring. If you have an SNMP manager that can log these events, you should enable these messages in case an intruder causes a shutdown of the monitoring service.Enable SNMP authentication trapsIf an SNMP manager uses an incorrect password when trying to poll the bridge, it could represent an intruder trying to probe the monitoring device. In this case, an SNMP authentication failure trap message is sent if this option is enabled.SNMP IP access listThis identifies the SNMP managers that can poll the router.If you want remote monitoring to be used as a screening router, select Security Firewall setup. You should see a screen showing the protocol options for which you set filters. The protocol options are TCP/UDP, AppleTalk, DECNET, and Novell’s IPX. If you select the TCP/UDP option, you should see a screen for programming the filter.
