Configuring an 802.1X client MAC address
The authenticator adds the MAC address of an authenticated 802.1X client to the MAC address table and then assigns access rights to the client.
If the device acting as an 802.1X client has multiple Ethernet interfaces to seek MACsec protection, configure a unique MAC address for each interface to ensure successful 802.1X client authentication. For information about MACsec, see "Configuring MACsec."
You can use either of the following methods to configure a unique MAC address for each interface:
Execute the mac-address command in Ethernet interface view. For information about this command, see Layer 2—LAN Switching Command Reference.
Configure an 802.1X client MAC address.
To configure an 802.1X client MAC address on an interface:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter Ethernet interface view. | interface interface-type interface-number | N/A |
3. Configure an 802.1X client MAC address. | dot1x supplicant mac-address mac-address | By default, an Ethernet interface uses the interface's MAC address for 802.1X client authentication. If the interface's MAC address is unavailable, the interface uses the device's MAC address for 802.1X client authentication. |
