Configuring 802.1x Authentication
Configuring the Host Mode
Beginning in privileged EXEC mode, follow these steps to allow a single host (client) or multiple hosts
on an 802.1x-authorized port. Use the multi-domain keyword to configure multidomain authentication
(MDA) to enable authentication of both a host and a voice device, such as an IP phone (Cisco or
non-Cisco) on the same switch port. This procedure is optional.
