Configuring SNMP as a Service and Adding Rules
By default, SNMP is disabled on the Dell SonicWALL security appliance. To enable SNMP, you must first enable SNMP on the System > SNMP 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.
If your SNMP management system supports discovery, the Dell SonicWALL security appliance agent automatically discover the Dell SonicWALL security appliance on the network. Otherwise, you must add the Dell SonicWALL security appliance to the list of SNMP-managed devices on the SNMP management system.
