Configure what triggers SNMP traps

The trap parameters define where and how SNMP traps are sent from Secure SD-WAN Engines and the SMC Appliance.

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

In addition to the general events, the tester on each Secure SD-WAN 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.

Steps

Select Configuration.
Browse to Other Elements > Engine Properties > SNMP Agents.
Open the SNMP Agent properties in one of the following ways:
- Right-click an existing SNMP Agent element, then select Properties.
- To create an SNMP Agent element, right-click SNMP Agents, then select New SNMP Agent.
In the Traps section, specify the sender of the SNMP trap.
- SNMPv1 — (Secure SD-WAN Engines only) In the Community field, enter a community string.
- SNMPv2c — In the Community field, enter a community string.
- SNMPv3 — From the User Name drop-down list, select a user name.
Click Add, then enter the IP address and UDP port where the traps are sent.
(Secure SD-WAN Engines only) In the Active Traps section, select the events for which you want to set a trap.
Click OK.
