Configuring the Login Authentication Mode

You can configure the following login authentication modes to authenticate administrator login attempts:

• Local authentication — The controller uses locally configured login credentials and passwords. See Configuring the Local Login Authentication Mode and Adding New Users.
• RADIUS authentication — The controller uses login credentials and passwords configured on a RADIUS server. See Configuring the RADIUS Login Authentication Mode.
• Local authentication first, then RADIUS authentication — The controller first uses locally configured login credentials and passwords. If this login fails, the controller attempts to validate login credentials and passwords configured on a RADIUS server. See Configuring the Local, RADIUS Login Authentication Mode.
• RADIUS authentication first, then local authentication — The controller first uses login credentials and passwords configured on a RADIUS server. If this login fails, the controller attempts to validate login credentials and passwords configured locally. See Configuring the RADIUS, Local Login Authentication Mode.
  

  Note

  The ExtremeWireless Appliance enables you to recover the controller via the Rescue mode if you have lost its login password. For more information, see the ExtremeWireless Maintenance Guide.
