444CHAPTER 21: CONFIGURING AAA FOR NETWORK USERS

Remote Authentication with Local Backup

You can use a combination of authentication methods; for example, PEAP offload and local authentication. When PEAP offload is configured, the WX switch offloads all EAP processing from server groups; the RADIUS servers are not required to communicate using the EAP protocols. (For details, see “Configuring EAP Offload” on page 449.) In the event that RADIUS servers are unavailable, local authentication takes place, using the database on the WX switch.

Suppose an administrator wants to rely on RADIUS servers and also wants to ensure that a certain group of users always gets access. As shown in the following example, the administrator can enable PEAP offload, so that authentication is performed by a RADIUS server group as the first method for these users, and configure local authentication last, in case the RADIUS servers are unavailable. (See Figure 31.)

1To configure server-1and server-2at IP addresses 192.168.253.1 and 192.168.253.2 with the password chey3nn3, the administrator enters the following commands:

WX1200# set radius server server-1 address 192.168.253.1 key chey3nn3 WX1200# set radius server server-2 address 192.168.253.2 key chey3nn3

2To configure server-1 and server-2 into server-group-1, the administrator enters the following command:

WX1200# set server group server-group-1 members server-1 server-2

3To enable PEAP offload plus local authentication for all users of SSID mycorp at @example.com, the administrator enters the following command.

WX1200# set authentication dot1x ssid mycorp *@example.com pass-through server-group-1 local
