474 CHAPTER 46: 802.1X CONFIGURATION
Advanced 802.1x
Configuration
Advanced 802.1x configurations, as listed below, are all optional.
■ CAMS cooperation configuration, including multiple network adapters
detecting, proxy detecting, and so on.
■ Client version checking configuration
■ DHCP -triggered authentication
■ Guest VLAN configuration
Prerequisites Configuration of basic 802.1x
Configuring Proxy
Checking
This function needs the support of 802.1x client program and CAMS, as listed
below.
■ The 802.1x clients must be able to check whether multiple network cards,
proxy servers, or IE proxy servers are used on the user devices.
■ On CAMS, enable the function that forbids clients from using multiple network
cards, a proxy server, or an IE proxy.
By default, the use of multiple network cards, proxy server, and IE proxy are
allowed on 802.1x client. If you specify CAMS to disable use of multiple network
cards, proxy server, and IE proxy, CAMS sends messages to 802.1x client to request
the latter to disable the use of multiple network cards, proxy server, and IE proxy
when a user passes the authentication.
n
■ The proxy checking function needs the support of 3Com’s 802.1x client
program.
■ The configuration listed in Table 362 takes effect only when it is performed on
CAMS as well as on the switch and the client version checking function is
enabled on the switch (by the dot1x version-check command).
