Question

A network engineer wants ISE to profile IP phones and access points more accurately. The RADIUS probe alone is not returning enough attributes, and the engineer needs ISE to actively pull CDP and LLDP cache data from switches to identify these endpoints by their neighbor-reported device information. Which profiler probe should be enabled to actively poll the switch for this data?

Accepted Answer

The SNMP Query probe, which polls the NAD for CDP/LLDP and interface data

Answer

The DHCP probe, which parses DHCP option 60 vendor class identifiers

Answer

The NetFlow probe, which collects traffic flow records from the switch

Answer

The HTTP probe, which captures user-agent strings from web traffic
