3Com Switch 8800 Configuration Guide Chapter 39 802.1x Configuration
39-3
802.1x provides an implementation solution of user ID authentication. However, 802.1x
itself is not enough to implement the scheme. The administrator of the access device
should configure the AAA scheme by selecting RADIUS or local authentication so as to
assist 802.1x to implement the user ID authentication. For detailed description of AAA,
refer to the corresponding AAA configuration.
39.1.4 Implementing 802.1x on Ethernet Switches
The Switch 8800 not only supports the port access authentication method regulated by
802.1x, but also extends and optimizes it in the following way:
z Support to connect several End Stations in the downstream via a physical port.
z The access control (or the user authentication method) can be based on port or
MAC address.
In this way, the system becomes much securer and easier to manage.
39.2 802.1x Configuration The configuration tasks of 802.1x itself can be fulfilled in system view of the Ethernet
switch. After the global 802.1x is enabled, the user can configure the 802.1x state of the
port. The configured items will take effect after the global 802.1x is enabled.
Note:
When 802.1x is enabled on a port, the max number of MAC address learning which is
configured by the command mac-address max-mac-count cannot be configured on
the port, and vice versa.
The following sections describe 802.1x configuration tasks.
z Enabling/Disabling 802.1x
z Setting the Port Access Control Mode
z Setting Port Access Control Method
