Setting Up Port-Based Network Access Control

Configuring 802.1X

page 37-8

OmniSwitch AOS Release 6 Network Configuration Guide

For port-based network access control, 802.1X must be enabled for the switch and the switch must know 
which servers to use for authenticating 802.1X supplicants. 

In addition, 802.1X must be enabled on each port that is connected to an 802.1X supplicant (or device). 
Optional parameters may be set for each 802.1X port.

The following sections describe these procedures in detail.

Use the 

 command to enable 802.1X for the switch and specify an authentica-

tion server (or servers) to be used for authenticating 802.1X ports. The servers must already be configured 
through the 

 command. An example of specifying authentication servers for authenticat-

ing all 802.1X ports on the switch:

-> aaa authentication 802.1x rad1 rad2

In this example, the rad1 server will be used for authenticating 802.1X ports. If rad1 becomes unavail-
able, the switch will use rad2 for 802.1X authentication. When this command is used, 802.1X is automati-
cally enabled for the switch.

Use the 

 command to enable MAC authentication for the switch and specify an 

authentication server (or servers) to be used for authenticating non-supplicants on 802.1x ports. As with 
enabling 802.1x authentication, the servers specified with this command must already be configured 
through the 

The following example command specifies authentication servers for authenticating non-supplicant 
devices on 802.1x ports:

-> aaa authentication mac rad1 rad2

Note that the same RADIUS servers can be used for 802.1x (supplicant) and MAC (non-supplicant) 
authentication. Using different servers for each type of authentication is allowed but not required.

For more information about using MAC authentication and classifying non-supplicant devices, see 

To enable 802.1X on a port, use the 

 command. The port must also be configured as a 

mobile port.

-> vlan port mobile 3/1

-> vlan port 3/1 802.1x enable

The vlan port 802.1x command enables 802.1X on port 1 of slot 3. The port will be set up with defaults 
listed in 

.

To disable 802.1X on a port, use the disable option with vlan port 802.1x command. For more informa-
tion about vlan port commands, See
