Enabling and Configuring SNMP

When SNMP is enabled, SNMP traps are automatically triggered for many events that are generated by SonicWall Security Services such as Intrusion Prevention and Gateway Anti-Virus.

More than 50 IPS and GAV events currently trigger SNMP traps. The SonicOS Log Event Reference Guide contains a list of events that are logged by SonicOS, and includes the SNMP trap number where applicable. The guide is available online at https://support.sonicwall.com/technical-documents.

To determine the traps that are possible when using IPS Sniffer Mode with Intrusion Prevention enabled, search for Intrusion in the table found in the Index of Log Event Messages section in the SonicOS Log Event Reference Guide. The SNMP trap number, if available for that event, is printed in the SNMP Trap Type column of the table.

To determine the possible traps with Gateway Anti-Virus enabled, search the table for Security Services, and view the SNMP trap number in the SNMP Trap Type column.
