Advanced Management

Enable SNMP

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, select the Enable SNMP check box, and then click Configure in the System > Administration page.

 Note: v1 traps are not supported on the SonicWALL security appliance.
1	Enter the host name of the SonicWALL security appliance in the System Name field.
2	Enter the network administrator’s name in the System Contact field.
3	Enter an e-mail address, telephone number, or pager number in the System Location field.
4	Enter a name for a group or community of administrators who can view SNMP data in the Get
	Community Name field.
5	Enter a name for a group or community of administrators who can view SNMP traps in the Trap
	Community Name field.
6	Enter the IP address or host name of the SNMP management system receiving SNMP traps in the
	Host 1 through Host 4 fields. You must configure at least one IP address or host name, but up to
	four addresses or host names can be used.
7	Click OK.

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, the SonicWALL security appliance responds only to Get SNMP messages received on its LAN interface. Appropriate rules must be configured to allow SNMP traffic to and from the WAN interface. SNMP trap messages can be sent via the LAN or WAN.

Note: Refer to Chapter 4, Configuring Firewall Settings for instructions on adding services and rules to the SonicWALL security appliance.

If your SNMP management system supports discovery, the SonicWALL 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.
