When classifying IoT devices, which two methods does Prisma SD-WAN use to discover devices that are not directly connected to the branch ION?
Prisma SD-WAN uses SNMP with LLDP to discover IoT devices that are not directly connected to a branch ION. LLDP supplies neighbor information, and the ION uses SNMP MIB queries to retrieve IP and MAC address bindings while crawling neighboring devices. Cisco Discovery Protocol (CDP) is not supported for this discovery, and Syslog is used for log export rather than device discovery.
