Setting the port security mode

You can specify a port security mode when port security is disabled, but your configuration cannot take effect.

Changing the port security mode of a port logs off the online users of the port.

Do not enable 802.1X authentication or MAC authentication on a port where port security is enabled.

After enabling port security, you can change the port security mode of a port only when the port is operating in noRestrictions (the default) mode. To change the port security mode for a port in any other mode, first use the undo port-security port-mode command to restore the default port security mode.

The device supports the URL attribute assigned by a RADIUS server in the following port security modes:

• mac-authentication.

• mac-else-userlogin-secure.

• mac-else-userlogin-secure-ext.

• userlogin-secure.

• userlogin-secure-ext.

• userlogin-secure-or-mac.

• userlogin-secure-or-mac-ext.

• userlogin-withoui.

During authentication, the HTTP or HTTPS requests of a user are redirected to the Web interface specified by the server-assigned URL attribute. After the user passes the Web authentication, the RADIUS server records the MAC address of the user and uses a DM (Disconnect Message) to log off the user. When the user initiates 802.1X or MAC authentication again, it will pass the authentication and come online successfully.

To redirect the HTTPS requests of port security users, specify the HTTPS redirect listening port on the device. For more information, see HTTP redirect in Layer 3—IP Services Configuration Guide.

Before you set a port security mode for a port, complete the following tasks:

• Disable 802.1X and MAC authentication.

• Verify that the port does not belong to any service loopback group.

• If you are configuring the autoLearn mode, set port security's limit on the number of secure MAC addresses. You cannot change the setting when the port is operating in autoLearn mode.

1. Enter system view.

   system-view

2. Set an OUI value for user authentication.

   port-security oui index index-value mac-address oui-value

   By default, no OUI values are configured for user authentication.

   This command is required only for the userlogin-withoui mode.

   You can set multiple OUIs, but when the port security mode is userlogin-withoui, the port allows one 802.1X user and only one user that matches one of the specified OUIs.

3. Enter interface view.

   interface interface-type interface-number

4. Set the port security mode.

   port-security port-mode { autolearn | mac-authentication | mac-else-userlogin-secure | mac-else-userlogin-secure-ext | secure | userlogin | userlogin-secure | userlogin-secure-ext | userlogin-secure-or-mac | userlogin-secure-or-mac-ext | userlogin-withoui }

   By default, a port operates in noRestrictions mode.
