Example for Configuring Airtime Fair Scheduling
Networking Requirements
Enterprise users can access the network through WLANs, which is the basic requirement of mobile office. Furthermore, users' services are not affected during roaming in the coverage area.
The administrator requires that multiple users on the network be able to fairly use network bandwidth to improve overall user experience.

Configuration Roadmap
- Enable airtime fair scheduling to ensure that multiple users on a radio can fairly use network bandwidth to improve overall user experience.
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.
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 airtime fair scheduling.
# Choose
.# In the AP group list, click ap-group1. Click
in front of Radio Management. Under it, click
in front of radio 0.
# Click
in front of 2G Radio Profile, and click RRM Profile. Click Create. On the page that is displayed, set Profile name to wlan-rrm and click OK. The RRM Profile configuration page is displayed.
# Enable airtime fair scheduling in the RRM profile.
# Click Apply. In the dialog box that is displayed, click OK.
- Verify the configuration.
- Users can fairly use network bandwidth, improving overall user experience.
