Configure what triggers SNMP traps

The trap parameters define where and how SNMP traps are sent from Engines and the Appliance.

The same SNMP Agent element can be used for Engines and the Appliance. Some settings only apply to Engines. Settings that are not supported for the Appliance are ignored when the SNMP Agent is used for the Appliance.

In addition to the general events, the tester on each Engine can send SNMP traps when a test fails.

Note: If the Destinations field is left empty, no traps are sent, and the other trap parameters are ignored. If the Destinations field has a value, the rest of the trap parameters must also have a value.
