Configuring an MBA Network

To create the MBA network associated to a Default Auth Role accept policy. Take the following steps:

  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

      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.
    • Enable MAC-based authentication (MBA) and choose an appropriate MBA Timeout Role.
    • Clear the Authenticate Locally for MAC check box.
    • Choose RADIUS as the Authentication Method and select the NAC added in Step 1 as the Primary RADIUS.
    • Select a Default VLAN.
    • Click Save.
  3. Add a new rule.
    • From ExtremeCloud IQ Controller, navigate to Onboard > Rules.
    • Click Add.
    • In the Location Group drop-down menu, select Network: <name of your network>.
    • From the Accept Policy field:
      • To configure a Default Auth Role Policy: select Use Default Auth Role.
      • To configure a Pass-thru External RADIUS Accept Policy: select Pass Through External RADIUS.
    • Save the rule.
  4. Assign the network created previously and its Default Auth Role to a site and save. Take the following steps:
    • Go to Configure > Sites and select a site.
    • Click the Device Groups tab and select a device group.
    • Beside the Profile field, click 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.
Finally, associate clients to the SSID of the network. The Access-Request is sent to the external NAC server. The NAC server matches the MAC address of the user with one of the MAC addresses in the End-System Group (that was created earlier) and sends an Access-Accept with a Filter-ID Enterprise User. The ExtremeCloud IQ Controller Access Control engine ignores the Filter-ID and applies the Default Auth Role that was configured under Network Settings.
