Create an SNMP Agent for SNMP version 1 or 2c

Configure an SNMP Agent for SNMP version 1 or 2c so that Secure SD-WAN Engines can share network management information using the SNMP protocol, or for SNMP version 2c so that the SMC Appliance can share network management information using the SNMP protocol.

Note: The SMC Appliance does not support SNMP v1.
