Configuring the 802.1X Supplicant
Traditionally, the dot1x authenticator/client relationship has always been a network device and a PC
client respectively, as it was the PC user that had to authenticate to gain access to the network. However,
wireless networks introduce unique challenges to the traditional authenticator/client relationship. First,
access points can be placed in public places, inviting the possibility that they could be unplugged and
their network connection used by an outsider. Second, when a repeater access point is incorporated into
a wireless network, the repeater access point must authenticate to the root access point in the same way
as a client does.
The supplicant is configured in two phases:
• Create and configure a credentials profile
• Apply the credentials to an interface or SSID
You can complete the phases in any order, but they must be completed before the supplicant becomes
operational.
Creating a Credentials Profile
Beginning in privileged EXEC mode, follow these steps to create an 802.1X credentials profile:
Use the no form of the dot1x credentials command to negate a parameter.
