Configuration Procedure for NAC

Configuration Procedure for NAC

Pre-configuration Tasks

NAC only provides multiple network access control protocols for users. To completely authenticate user identity and control users' network access rights, complete the following AAA configuration tasks before configuring NAC:

  • Configure the domain and AAA scheme.
  • Configure the user name and password on the RADIUS or HWTACACS server if RADIUS or HWTACACS authentication is used.
  • Configure the user name and password on the network access device if local authentication is used.

For details about how to configure the AAA client, see AAA Configuration.

NAC Configuration Tasks

Authentication Mode



802.1X authentication

Users are densely distributed and high information security is required.

MAC Address authentication

Dumb terminals such as printers and fax machines need to connect to the network.

Portal authentication

Users are sparsely distributed and move frequently.

Multi-mode authentication

The device allows multiple authentication modes to be deployed simultaneously to meet various authentication requirements on the network.

To configure multi-mode authentication of several authentication modes, you only need to bind corresponding access profiles to an authentication profile. The device triggers the corresponding authentication based on received authentication packets.
