The NPS Server which is the authentication server then informs the authenticator whether or not the authentication attempt succeeded, at which point “Lady Smith” is either granted or denied access to the LAN behind the switch. Message exchanges take place between the supplicant and the authenticator which is the Aruba 2920 Switch, and the authenticator passes the supplicant’s credentials which is her (Windows Active Directory User Account Credentials) to the authentication server for verification.
The laptop computer must therefore act in a supplicant role. Her laptop computer is connected to a port on the Aruba 2920 Edge Switch that has 802.1x port authentication control enabled. There are multiple VLANs with resources available based on user vlan membership. In this scenario, “Lady Smith” wishes to use services offered by servers on the LAN behind the switch. How to Provision 802.1 X Authentication Step By Step With Dynamic VLAN Assignment With Windows Radius Server For 802.1x Clients.Ī typical configuration for a system under IEEE 802.1x Authentication control is shown in the following figure. Open Lounge with IEEE 802.1X Authentication with Dynamic VLAN for all users to function as if they were at their own desks Meeting rooms could for a moment have the accounting group or the development group meeting there and based on the intelligent and dynamic vlan assignmnet with 802.1x authentication, users port-access are defined their appropriate vlans for their respective access to resources on the network. It is only wise to incorporate IEEE 802.1X Authentication and Dynamic VLAN Assignment with NPS Radius Server in areas where you expect different teams to come to. Tying them to a local VLAN may only be helpful if they are bound to desks in those locations, although the most ideal outcome, it is not the most practical.
User location cannot be predicted as they may be at and out of a desk and up and about should they need to do so. IEEE 802.1X Authentication and Dynamic VLAN Assignment with NPS Radius Server is an important element to networking in the real world.
