Question

A network administrator wants ISE to be notified whenever an endpoint connects to or disconnects from an access-layer switch, so that the profiler receives a triggered notification rather than relying on ISE to periodically poll every switch for its full interface and CAM table data. Which profiler probe should be enabled on the PSN, and how must the switch be configured to support it?

Accepted Answer

Enable the SNMP Trap probe on the PSN and configure the switch to send MAC notification and link-up/link-down traps to ISE, which then triggers an SNMP Query for detailed attributes

Answer

Enable the SNMP Query probe on the PSN and configure a polling interval so ISE reads the switch CAM and ARP tables at fixed intervals

Answer

Enable the NetFlow probe on the PSN and configure the switch to export flow records to ISE for endpoint connection tracking

Answer

Enable the DHCP probe on the PSN and configure ip helper-address on the switch SVI to forward DHCP requests to ISE
