Service Requirements

To improve user experience and reduce burden on the 2.4 GHz frequency band, customers require that STAs preferentially connect to the 5 GHz frequency band.

Networking Requirements

As shown in Figure 2-10, 2.4 GHz and 5 GHz wireless networks are deployed in the conference hall. The AP works on dual frequency bands. STAs connected to the APs support both 2.4 GHz and 5 GHz frequency bands.

Item Data

VAP profile

  • Name: wlan-net

  • Band steering function: enabled
  • Referenced profile: SSID profile wlan-net and security profile wlan-net

RRM profile

  • Name: default

  • Start threshold for load balancing between radios: 15

  • Load difference threshold for load balancing between radios: 25

Configuration Roadmap

Configure the band steering function and proper band steering parameters so that users can preferentially access the 5 GHz frequency band.

Configuration Notes

  • Use AP that supports both 5 GHz and 2.4 GHz frequency bands and configure the same SSID and security policy on the 5 GHz and 2.4 GHz radios.
  • To allow a STA to preferentially associate with the 5 GHz radio and achieve a better access effect, configure larger power for the 5 GHz radio than the 2.4 GHz radio.
  • 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 on switch interfaces connected to APs 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. 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?.

Procedure

  1. Configure the band steering function.
    1. Enable the band steering function in the VAP profile wlan-net. By default, the band steering function is enabled.

      # Choose Configuration > WLAN Service > Profile.

      # Choose Wireless Service > VAP Profile in Profile Management. The VAP Profile List page is displayed.

      # Click wlan-net. The VAP profile page is displayed.

      # On the Advanced Configuration tab, enable the band steering function on the VAP profile page.

    2. # In the RRM profile, configure load balancing between radios to prevent heavy load on a single radio. Set the start threshold for load balancing between radios to 15, and the load difference threshold to 25%.

      # Choose Configuration > WLAN Service > Profile Management.

      # Choose Radio Management > RRM Profile in Profile Management. The RRM Profile List page is displayed.

      # Click the RRM profile default. The RRM profile configuration page is displayed.

      # On the Advanced Configuration tab, set the start threshold for load balancing between radios to 15, and the load difference threshold to 25%.

      # Click Apply. In the dialog box that is displayed, click OK.

  2. Verify the configuration.

    Choose Monitoring > Terminal Manage > STA Statistics. Most STAs can connect to the 5 GHz frequency band, and users enjoy good service experience.
