Guest VLAN
Configuration
The Guest VLAN function enables supplicant systems that are not authenticated to
access specific resources and thus perform the corresponding operations, such as
obtaining 802.1x client, upgrading client, or obtaining other upgrading programs.
With the Guest VLAN function enabled, supplicant systems that do not have 802.1x
client installed can access specific network resources. And those that have 802.1x
client installed can upgrade their 802.1x clients without being authenticated.
