GSS Series User Manual

3.2.8 802.1x

The 802.1x port-based network access control provides a method to restrict users to access

network resources via authenticating user’s information. This restricts users from gaining

access to the network resources through an 802.1x-enabled port without authentication. Any

user wishing to access the network through a port under 802.1x control, must first input their

account name for authentication and then wait for the authorisation to complete before

sending or receiving any data from an 802.1x-enabled port.

Before the devices or end stations can access the network resources through the ports under

802.1x control, the devices or end stations connected to a controlled port send the

authentication request to the authenticator, the authenticator passes the request to the

authentication server to authenticate and verify the username and password, and the server

then tells the authenticator if the request has been granted access for that port.
