Operation Manual – 802.1x and System Guard
H3C S3100-52P Ethernet switch
Note:
H3C's CAMS Server is a service management system used to manage networks and to
secure networks and user information. With the cooperation of other networking
devices (such as switches) in the network, a CAMS server can implement the AAA
functions and rights management.
I. Checking the supplicant system
An S3100-52P switch checks:
Supplicant systems logging on through proxies
Supplicant systems logging on through IE proxies
Whether or not a supplicant system logs in through more than one network
adapters (that is, whether or not more than one network adapters are active in a
supplicant system when the supplicant system logs in).
In response to any of the three cases, a switch can optionally take the following
measures:
Only disconnects the supplicant system but sends no Trap packets.
Sends Trap packets without disconnecting the supplicant system.
This function needs the cooperation of 802.1x client and a CAMS server.
The 802.1x client needs to be capable of detecting multiple network adapters,
proxies, and IE proxies.
The CAMS server is configured to disable the use of multiple network adapters,
proxies, or IE proxies.
By default, an 802.1x client program allows use of multiple network adapters, proxies,
and IE proxies. In this case, if the CAMS server is configured to disable use of multiple
network adapters, proxies, or IE proxies, it prompts the 802.1x client to disable use of
multiple network adapters, proxies, or IE proxies through messages after the supplicant
system passes the authentication.
Note:
The client-checking function needs the support of H3C's 802.1x client program.
To implement the proxy detecting function, you need to enable the function on both
the 802.1x client program and the CAMS server in addition to enabling the client
version detecting function on the switch by using the dot1x version-check
command.
