Configuring a AAA Network

On ExtremeCloud IQ Controller:

Use the IP address of the external NAC server as the primary RADIUS server.

1. Configure a RADIUS server for AAA authentication.
   • Log in to ExtremeCloud IQ Controller and go to Onboard > AAA > Radius Server and add a new RADIUS server.
   • Configure the following parameters:

     Radius Server IP Address

     Add the NAC IP address

     Shared Secret

     Provide the NAC Shared Secret.

     

     Note

     To find the Shared Secret of the NAC Manager, go to:

     Advanced NAC Configuration Settings > Global and Appliance Settings > Appliance Settings.

2. Create a new network.
   Configure the following parameters:

   Auth Type

   WPA2 Enterprise w/ RADIUS

   Authentication Method

   RADIUS

   Primary RADIUS

   IP Address of the External NAC added in Step 1.

   Default Auth Role

   Select a role other than Enterprise User.

   Default VLAN

   Select a Default VLAN. B@AP VLAN ID

   

   Note

   Both B@AP and B@AC are supported for NAC.

3. Select Save.
4. Create a policy rule.
   Go to Onboard > Rules and configure the following parameters:

   Location Group

   Network: <name of your network>

   Accept Policy

   • To configure a Default Auth Role Policy, select Use Default Auth Role.
   • To configure a Pass-Through External RADIUS Accept Policy, select Pass Through External RADIUS.

5. Select Save.

On the NAC Manager:

6. Edit the rule you created on ExtremeCloud IQ Controller here.
   Configure the following parameters:

   Authentication Method

   802.1x

   End-System Group

   Any

7. Select Save and enforce the NAC.

On ExtremeCloud IQ Controller:

8. Assign the network created previously and its Default Auth Role to a site and save.
   • Go to Configure > Sites and select a site.
   • Select the Device Groups tab and select a device group.
   • Beside the Profile field, select to edit the device group profile.
   • Go to the Networks tab and select the configured network.
   • Go to the Roles tab and select the configured Default Auth Role.

Associate clients to the SSID of the Network, when prompted for the username and password, use the username and password created with the New User. The external NAC server matches the rule you created under New Rule and upon successful authentication sends an Access-Accept and a Filter-ID Enterprise User. The ExtremeCloud IQ Controller Access Control engine applies the Enterprise User Role instead of the Default Auth Role that was configured under Network Settings.

Note

The Enterprise User role must exist on ExtremeCloud IQ Controller and must be assigned to the same device group as the client in order to be applied.
