Update: Enters the specified MAC address and
permission setting into the local database.

MAC Authentication Table: Displays current entries in the local
MAC database.
Note:
Client station MAC authentication occurs prior to the IEEE 802.1x
authentication procedure configured for the access point.
However, a client’s MAC address provides relatively weak user
authentication, since MAC addresses can be easily captured and
used by another station to break into the network. Using 802.1x
provides more robust user authentication using user names and
passwords or digital certificates. So, although you can configure
the access point to use MAC address and 802.1x authentication
together, it is better to choose one or the other, as appropriate.
Use MAC address authentication for a small network with a
limited number of users. MAC addresses can be manually
configured on the access point itself without the need to set up a
RADIUS server. Use IEEE 802.1x authentication for networks
with a larger number of users and where security is the most
important issue. For 802.1x authentication a RADIUS server is
required in the wired network to control the user credentials of the
wireless clients.
802.1x Setup
– IEEE 802.1x is a standard framework for network
access control that uses a central RADIUS server for user
authentication. This control feature prevents unauthorized access
to the network by requiring an 802.1x client application to submit
user credentials for authentication. The 802.1x standard uses the
Extensible Authentication Protocol (EAP) to pass user credentials
(either digital certificates, user names and passwords, or other)
from the client to the RADIUS server. Client authentication is then
verified on the RADIUS server before the access point grants
client access to the network.
