Operation Manual – 802.1x
Quidway S3100 Series Ethernet Switches
Note:
The client-version-checking function needs the support of Huawei's 802.1x client
program.
III. The Guest VLAN function
The Guest VLAN function enables supplicant systems that do not pass the
authentication to access a LAN in a restrained way.
With the Guest VLAN function enabled, supplicant systems that do not have 802.1x
client installed can access specific network resources. They can also upgrade their
802.1x clients without being authenticated.
With this function enabled:
The switch broadcasts active authentication packets to all 802.1x-enabled ports.
After the maximum number of authentication retries have been made and there
are still ports that have not sent any response back, the switch will then add these
ports into the Guest VLAN.
When the maximum number of authentication retries is reached, the switch adds
the ports that do not return response packets to Guest VLAN.
Users belonging to the Guest VLAN can access the resources of the Guest VLAN
without being authenticated. But they need to be authenticated before accessing
external resources.
Normally, the Guest VLAN function is coupled with the dynamic VLAN delivery function.
1.2 802.1x Configuration
802.1x provides a solution for authenticating users. To implement this solution, you
need to execute 802.1x-related commands. You also need to configure AAA schemes
on switches and to specify the authentication scheme (RADIUS authentication scheme
or local authentication scheme).

802.1x users use domain names to associate with the ISP domains configured on
switches
Configure the AAA scheme (a local authentication scheme or the RADIUS scheme)
to be adopted in the ISP domain.
