NAC Application

NAC Application

Context

After an authentication profile is bound to the interface, NAC is enabled in the interface. The device implements access control on users who go online through the interface.

An authentication profile uniformly manages NAC configuration. The authentication profile is bound to the interface or VAP profile view to enable NAC, implementing access control on the users in the interface or VAP profile. The authentication type of the users in the interface or VAP profile is determined by the access profile bound to the authentication profile. For details about how to configure an access profile, see Configuring an Access Profile.

When configuring NAC, pay attention to the following points:
  • Layer 2 physical interfaces, Layer 3 physical interfaces, routed main interfaces, VLANIF interfaces, WAN-side interfaces, port groups support NAC. The support for authentication types on different interfaces is as follows:
    • Layer 2 physical interfaces: 802.1X authentication, MAC address authentication, and Layer 2 Portal authentication
    • Layer 3 physical interfaces and routed main interface: Layer 3 Portal authentication
      NOTE:

      In wireless scenarios, it does not support Layer 3 Portal authentication.

    • VLANIF interfaces: Layer 2 Portal authentication, MAC address-prioritized Portal authentication in Fat AP Wi-Fi scenarios, and Layer 3 Portal authentication.
    • WAN-side interfaces: Layer 3 Portal authentication
  • Physical interfaces do not support multi-mode authentication modes containing Portal authentication.
  • For the access of wireless users through APs, ensure that the APs can be authenticated (for example, adding the APs to static users) when NAC authentication is deployed for users. Otherwise, the wireless users cannot be authenticated.
  • NAC authentication cannot be enabled both on a Layer 2 Ethernet interface and the VLANIF interface mapping the VLAN of the Ethernet interface. Otherwise, the users have no network access rights after connecting to the network.

  • After enabling NAC on an interface, you cannot run the following commands on the interface. Similarly, after running the following commands on an interface, you cannot enable NAC on the interface.

    Command

    Function

    mac-limit

    Sets the maximum number of MAC addresses that can be learned by an interface.

    mac-address learning disable

    Disables MAC address learning on an interface.

    port-security enable

    Enables port security.

Prerequisites

An authentication profile has been configured. For details about how to configure an authentication profile, see Configuring an Authentication Profile.

Procedure

  • Enable NAC on an interface.

    1. Run system-view

      The system view is displayed.

    2. Run interface interface-type interface-number

      The interface view is displayed.

    3. Run authentication-profile authentication-profile-name

      The authentication profile is applied to the interface.

      By default, no authentication profile is applied to an interface.

    NOTE:
    In wireless access scenario, pay attention to the following points:
    • When an authentication profile is bound to a portal access profile, the authentication profile can be applied to VLANIF interface or WLAN-BSS interface (FAT-AP mode).
    • When both MAC and portal access profiles are bound to an authentication profile and MAC address-prioritized Portal authentication is enabled, the authentication profile can only be applied to VLANIF interfaces.

Verifying the Configuration

Run the display authentication interface interface-type interface-number command to view the configuration of the NAC authentication mode on an interface.
