3Com Switch 7750 Series
Command Reference Guide – 802.1x Chapter 1 802.1x Configuration Commands
1-17
z The 802.1x supplicant system must be able to detect whether the client uses
multiple network cards, a proxy, or IE proxy;
z CAMS has disabled the use of multiple network cards, a proxy server, and an IE
proxy server.
By default, an 802.1x supplicant system enables the use of multiple network cards,
proxies, or IE proxies. If CAMS has these features disabled, it would notify the 802.1
supplicant system to have the corresponding features disabled as well after the latter
has successfully passed the authentication.
Note:
z The supplicant system proxy checking function needs the support of 3Com's 802.1x
client program (V1.29 or later version).
z The supplicant system proxy checking function takes effect only after it has been
enabled on CAMS and the client version checking function is enabled on the switch
(using the dot1x version-check command).
Related command: display dot1x.
