Configuring The Host Mode - Cisco IE-3000-8TC Software Configuration Manual

Chapter 12 Configuring IEEE 802.1x Port-Based Authentication
This example shows how to specify the server with IP address 172.20.39.46 as the RADIUS server, to
use port 1612 as the authorization port, and to set the encryption key to rad123, matching the key on the
RADIUS server:
Switch(config)# radius-server host 172.l20.39.46 auth-port 1612 key rad123
You can globally configure the timeout, retransmission, and encryption key values for all RADIUS
servers by using the radius-server host global configuration command. If you want to configure these
options on a per-server basis, use the radius-server timeout, radius-server retransmit and the
radius-server key global configuration commands. For more information, see the
for All RADIUS Servers" section on page
You also need to configure some settings on the RADIUS server. These settings include the IP address
of the switch and the key string to be shared by both the server and the switch. For more information,
see the RADIUS server documentation.

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 that has the dot1x port-control interface configuration command set to
auto. 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.
