SNMP-based Discovery for IoT

Learn how branch ION devices use SNMP to discover IoT devices within the branch.

Prisma SD-WAN supports the discovery of devices that are not directly connected to the Prisma SD-WAN branch ION devices by using SNMP (Simple Network Management Protocol) to discover IoT devices within a branch network.

The system uses LLDP (Link Layer Discovery Protocol) to identify neighboring networking devices in a branch ION, launching an SNMP MIB to gather IP address and MAC Address entries. SNMP discovery involves querying LLDP information for IP and MAC address bindings, retrieving data from neighboring devices one by one until it discovers all the IoT devices. The ION device transmits these discovered bindings, alongside VLAN, subnet details, and so on, as Enhanced Application logs (EAL) to Strata Logging Service. IoT Security uses this information to enhance visibility in its portal by identifying the devices.
