Service Requirements

An enterprise needs to provide WLAN services for management personnel so that they can connect to the enterprise network from anywhere at any time. Furthermore, users' services are not affected during roaming in the coverage area.

Due to a small number of management personnel in the enterprise, MAC addresses of their STAs can be added to a STA whitelist. In this manner, STAs of other employees cannot connect to the WLAN.

In addition, network administrators have detected unauthorized access of some STAs and need to deny access of them. The administrators can add MAC addresses of these STAs to the blacklist, while other authorized STAs can still connect to the WLAN.

Networking Requirements

AC networking mode: Layer 2 networking in 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

Configuration Roadmap

Configure basic WLAN services to ensure that users can access the WLAN.
Configure a STA whitelist. Add MAC addresses of management personnel's wireless terminals to the whitelist. To prevent configuration impacts on other VAPs, configure the STA whitelist for a VAP, instead of an AP.
Configure a STA blacklist for an AP. Add MAC addresses of some STAs to the blacklist to prevent the STAs from associating with the AP, ensuing WLAN network security.

The STA whitelist and blacklist cannot be configured simultaneously for a VAP or an AP, that is, the STA whitelist and blacklist cannot take effect at the same time in a VAP profile or an AP system profile.

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.
