Service Requirements

When users attempt to access the WLAN, they can use 802.1X clients for authentication. After entering the correct user names and passwords, users can connect to the Internet. Furthermore, users' services are not affected during roaming in the coverage area.

Networking Requirements

AC networking mode: Layer 2 bypass mode
DHCP deployment mode: The AC functions as the DHCP server to assign IP addresses to APs, and SwitchB functions as the DHCP server to assign IP addresses to STAs.
Service data forwarding mode: direct forwarding
WLAN authentication mode: WPA-WPA2+802.1X+AES

Configuration Roadmap

Configure network interworking of the AC, APs, and other network devices.
Select Config Wizard to configure AC system parameters.
Select Config Wizard to configure the APs to go online on the AC.
Select Config Wizard to configure WLAN services on the AC. When configuring the security policy, select 802.1X and RADIUS authentication, and set the RADIUS server parameters.
Configure third-party server interconnection parameters.

The AC and server must have the same RADIUS shared key.

Configuration Notes

No ACK mechanism is provided for multicast packet transmission on air interfaces. In addition, wireless links are unstable. To ensure stable transmission of multicast packets, they are usually sent at low rates. If a large number of such multicast packets are sent from the network side, the air interfaces may be congested. You are advised to configure multicast packet suppression to reduce impact of a large number of low-rate multicast packets on the wireless network. Exercise caution when configuring the rate limit; otherwise, the multicast services may be affected.
- In direct forwarding mode, you are advised to configure multicast packet suppression on switch interfaces connected to APs.
- In tunnel forwarding mode, you are advised to configure multicast packet suppression in traffic profiles of the AC.
For details on how to configure traffic suppression, see How Do I Configure Multicast Packet Suppression to Reduce Impact of a Large Number of Low-Rate Multicast Packets on the Wireless Network?.
Configure port isolation on the interfaces of the device directly connected to APs. If port isolation is not configured and direct forwarding is used, a large number of unnecessary broadcast packets may be generated in the VLAN, blocking the network and degrading user experience.
In tunnel forwarding mode, the management VLAN and service VLAN cannot be the same. Only packets from the management VLAN are transmitted between the AC and APs. Packets from the service VLAN are not allowed between the AC and APs.

Procedure

Configure the network devices.
