Snmp Daemon

EventSentry can receive SNMP v1, v2c and v3 traps from remote network devices. The SNMP trap daemon can either log incoming traps to the application event log, or store them in a database.

To activate the SNMP trap daemon, check the Enable SNMP Trap Daemon check box on the "General" tab and configure either the database or event log feature. The default SNMP port is 162, but can be changed to another port.

Threshold Settings

To limit the number of incoming traps that are processed by the daemon, change the maximum number of messages and the applicable time period. The daemon will drop incoming packets if the count exceeds the number specified in Maximum number of allowed messages for the configure Time Period.

Authorized IP Addresses / Networks

For enhanced security you will have to specify from which hosts the daemon will accept packets. Please note that host names are not allowed in the list, you can only specify IP addresses.

You can enter IP addresses with or without specifying the subnet bits. For example, if you only want to add two servers with the IP addresses 184.23.22.11 and 184.23.22.43, simply add those two IP addresses to the list.

If you want to allow a whole subnet, for example the IP addresses 184.23.22.1 - 184.23.22.254, then you will have to add 184.23.22.0/24. If you only want to allow the range 184.23.22.128 - 184.23.22.254 then you can specify 184.23.22.128/25.

Compatibility

The daemon should work with any SNMP compatible device that supports v1, v2c or v3.
