Question

A network administrator wants ISE to receive CDP, LLDP, and DHCP profiling data collected directly by the access switches, without configuring SPAN or a dedicated DHCP relay to ISE. The switches are Catalyst models that support Device Sensor. Which combination on the switch ensures ISE receives this data through the RADIUS probe?

Accepted Answer

Enable Device Sensor to capture CDP/LLDP/DHCP and configure RADIUS accounting so the attributes are sent to ISE in accounting updates

Answer

Configure an ip helper-address pointing to the ISE PSN and enable the DHCP probe on ISE

Answer

Enable the SNMP Query probe on ISE and configure SNMP community strings on each switch

Answer

Configure a SPAN session mirroring access ports to the ISE monitoring interface and enable the SPAN/NetFlow probe
