Authentication
Authentication
Phones running the 8.2(1) firmware load, or later, can utilize the 802.1X Link Layer
Authentication protocol to connect to a Catalyst® switch implementing this security
mechanism. A single downstream device, connected to the PC port, may also implement
802.1X Link Layer Authentication and the phone will pass through the EAPoL requests on a
proxy basis.
