SNMP (Simple Network Management Protocol) is a network protocol used over User Datagram Protocol (UDP) that allows network administrators to monitor the status of the SonicWALL security appliance and receive notification of critical events as they occur on the network. The SonicWALL security appliance supports SNMP v1/v2c and all relevant Management Information Base II (MIB) groups except egp and at . The SonicWALL security appliance replies to SNMP Get commands for MIBII via any interface and supports a custom SonicWALL MIB for generating trap messages. The custom SonicWALL MIB is available for download from the SonicWALL Web site and can be loaded into third-party SNMP management software such as HP Openview, Tivoli, or SNMPC.
To enable SNMP on the SonicWALL security appliance, log into the Management interface and click System , then Administration. Select the Enable SNMP checkbox, and then click Configure . The Configure SNMP window is displayed.

Trap messages are generated only for the alert message categories normally sent by the SonicWALL security appliance. For example, attacks, system errors, or blocked Web sites generate trap messages. If none of the categories are selected on the Log > Settings page, then no trap messages are generated.
By default, SNMP is disabled on the SonicWALL security appliance. To enable SNMP you must first enable SNMP on the System > Administration page, and then enable it for individual interfaces. To do this, go to the Network > Interfaces page and click on the Configure button for the interface you want to enable SNMP on.
For instructions on adding services and rules to the SonicWALL security appliance, see Part five Firewall.
If your SNMP management system supports discovery, the SonicWALL security appliance agent automatically discover the SonicWALL security appliance on the network. Otherwise, you must add the SonicWALL security appliance to the list of SNMP-managed devices on the SNMP management system.
