This function needs the cooperation of iNode client and a iMC server.
z
The iNode client needs to capable of detecting multiple network adapters, proxies, and IE proxies.
z
The iMC server is configured to disable the use of multiple network adapters, proxies, or IE proxies.
By default, an iNode client program allows use of multiple network adapters, proxies, and IE proxies. In
this case, if the iMC server is configured to disable use of multiple network adapters, proxies, or IE
proxies, it prompts the iNode client to disable use of multiple network adapters, proxies, or IE proxies
through messages after the supplicant system passes the authentication.
z
The client-checking function needs the support of iNode client program.
z
To implement the proxy detecting function, you need to enable the function on both the iNode client
program and the iMC server in addition to enabling the client version checking function on the
device by using the dot1x version-check command.
Checking the client version
With the iNode client version-checking function enabled, the device checks the version and validity of
an iNode client to prevent unauthorized users or users with earlier versions of iNode client from logging
in.
This function makes the device to send version-requesting packets again if the iNode client fails to send
version-reply packet to the device when the version-checking timer times out.
The iNode client version-checking function needs the support of an iNode client program.
The Guest VLAN function
The Guest VLAN function enables supplicant systems that are not authenticated to access network
resources in a restrained way.
The Guest VLAN function enables supplicant systems that do not have iNode client installed to access
specific network resources. It also enables supplicant systems that are not authenticated to upgrade
their iNode client programs.
With this function enabled:
z
The device sends authentication request (EAP-Request/Identity) packets to all the 802.1x-enabled
ports.
z
After the maximum number retries have been made and there are still ports that have not sent any
response back, the device will then add these ports to the Guest VLAN.
z
Users belonging to the Guest VLAN can access the resources of the Guest VLAN without being
authenticated. But they need to be authenticated when accessing external resources.
Normally, the Guest VLAN function is coupled with the dynamic VLAN delivery function.
