Service Requirements

To improve WLAN security, an enterprise uses the MAC address-prioritized Portal authentication mode to control user access.

Networking Requirements

AC networking mode: Layer 2 bypass mode
DHCP deployment mode:
- The AC functions as a DHCP server to assign IP addresses to APs.
- The aggregation switch (SwitchB) functions as a DHCP server to assign IP addresses to STAs.
Service data forwarding mode: tunnel forwarding
Authentication mode: MAC address-prioritized Portal authentication
Security policy: open

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.

1. The WLAN with the SSID wlan-net is available.
2. The STA can associate with the WLAN and obtain an IP address 10.23.101.x/24, and its gateway address is 10.23.101.2.
3. Choose Monitoring > User > User List. All online users are displayed in User List. You can use the filtering function to filter the display results. For example, click next to SSID. Set the filtering condition, enter wlan-net, and click OK. Users connected to the SSID wlan-net are displayed. Multi-column filtering is supported to accurately query online users.
4. When a user opens the browser and attempts to access the network, the user is automatically redirected to the authentication page provided by the Portal server. After entering the correct user name and password on the page, the user can access the network.
5. Assume that the MAC address validity period configured on the server is 60 minutes. If a user is disconnected from the wireless network for 5 minutes and reconnects to the network, the user can directly access the network. If a user is disconnected from the wireless network for 65 minutes and reconnects to the network, the user will be redirected to the Portal authentication page.
