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.
Note The 802.1X supplicant is available on 1040, 1130AG, 1140, 1240AG, 1250, 1260, and 1300 series access
points. It is not available on 1100 and 1200 series access points.
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.
