Configure Auto-sense Voice Information for IP Phones
The switch applies the voice configuration on Auto-sense-enabled ports, after it discovers IP phones on the port through Link Layer Discovery Protocol (LLDP) packets.
Before you begin
If you boot the switch with a configuration file, and not through Zero Touch Fabric Configuration, you must manually enable Auto-sense on specific ports.
About this task

- In a non NAC, a phone is classified based on the phones LLDP signaling.
- In a NAC, a phone is authenticated based on EAP/NEAP radius authenticated, or if configured, it is LLDP authenticated
