Native AC + NAC Solution: Parent (Core Switches) in an SVF System Functions as the Authentication Point

Networking Requirements

Core switches set up a CSS that functions as the core of the entire campus network to implement high network reliability and forwarding of a large amount of data. In addition, core switches are configured with the native AC function to manage APs and transmit wireless service traffic on the entire network, implementing wired and wireless convergence.

Aggregation switches set up stacks to implement device-level backup and increase the interface density and forwarding bandwidth.

There are a large number of wired and wireless access devices that are widely distributed. To implement unified management and configuration and reduce management costs, SVF is deployed on the network. Core, aggregation, and access switches set up an SVF system. In the SVF system, the CSS of core switches functions as the parent, and aggregation and access switches function as ASs. The parent manages and configures ASs in a unified manner.

In this example, core switches set up an SVF system, which functions as the gateway and authentication point for wired and wireless users on the entire network. These users can access the network only after being authenticated. The specific requirements are as follows:

• Agile Controller-Campus functions as both the access authentication server and user data source server.
• Users include employees and guests. Wired users use combined 802.1X + Portal authentication, and wireless users use 802.1X authentication and MAC address-prioritized Portal authentication.
• The authentication server delivers authorization ACLs to control network access rights of different users.

Data Plan

Procedure

1. Enable campus network connectivity. For details, see Native AC + SVF Solution: the Parent Containing Core Switches Functions as the Gateway for Wired and Wireless Users.

   For wireless users, the security policies in security profiles vary according to access authentication modes.

   User Access Authentication Mode	Security Policy
   MAC address authentication or Portal authentication	Open system authentication
   802.1X authentication	WPA/WPA2-802.1X authentication. WPA2 authentication is used in this example.

   For users who use 802.1X authentication, configure a security policy in security profile sec1 as follows:

   [CORE-wlan-sec-prof-sec1] security wpa2 dot1x aes

   For users who use MAC address-prioritized Portal authentication, configure a security policy in security profile sec2 as follows:

   [CORE-wlan-sec-prof-sec2] security open

2. Configure AAA on CORE.
   # Configure the RADIUS server template tem_rad and configure parameters for interconnection between CORE and the RADIUS server. The parameters include the IP addresses, port numbers, and shared keys of the RADIUS authentication and accounting servers.
