(Optional.) Enabling the periodic online user re-authentication function
Enabling 802.1X
Follow the guideline when you enable 802.1X:
• Do not enable 802.1X on a port that is in a link aggregation or service loopback group.
To enable 802.1X:
Step Command Remarks
1. Enter system view.
system-view N/A
2. Enable 802.1X globally.
dot1x
By default, 802.1X is disabled
globally.
3. Enter Ethernet interface
view.
interface interface-type interface-number N/A
4. Enable 802.1X on a port.
dot1x
By default, 802.1X is disabled
on a port.
Enabling EAP relay or EAP termination
When configuring EAP relay or EAP termination, consider the following factors:
•
Support of the RADIUS server for EAP packets
•
Authentication methods supported by the 802.1X client and the RADIUS server
If the client is using only MD5-Challenge EAP authentication or the "us password" EAP
authentication initiated by an H3C iNode 802.1X client, you can use both EAP termination and EAP relay.
To use EAP-TL, PEAP, or any other EAP authentication methods, you must use EAP relay. When you make
your decision, see " Comparing EAP relay and EAP termination " for help.
For more information about EAP relay and EAP termination, see " 802.1X authentication procedures ."
To configure EAP relay or EAP termination:
Step Command Remarks
1. Enter system
view.
system-view N/A
2. Configure EAP
relay or EAP
termination.
dot1x authentication-method
{ chap | eap | pap }
By default, the network access device performs EAP
termination and uses CHAP to communicate with the
RADIUS server.
Specify the
eap keyword to enable EAP termination.
Specify the chap or pap keyword to enable
CHAP-enabled or PAP-enabled EAP relay.
