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.

Voice, video, and data services are transmitted on the WLAN. The administrator requires that voice and video services of QQ and WeChat have a higher priority to ensure good user experience in these QQ and WeChat services.

Voice and video optimization

  • Applied protocols: QQ and WeChat

Configuration Roadmap

  1. Enable the SAC function.
  2. Configure optimization for voice and video services so that these QQ and WeChat services have a higher priority than data services.

Configuration Notes

  • The configuration of optimization for voice and video services supports only tunnel forwarding.

  • The multimedia air interface optimization and dynamic EDCA parameter adjustment functions are mutually exclusive.

  • 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

  1. Check the basic configuration of the WLAN.

    Check Item

    Command

    Data

    Check the AP group to which an AP belongs.

    display ap all

    AP group: ap-group1

    Check all profiles referenced by the AP group.

    display ap-group name ap-group1

    VAP profile: wlan-net

    NOTE:
    • If an AP has different configurations from that in the AP group, the configuration on the AP takes precedence.
    • A new profile takes effect only after being bound to an AP or an AP group.

  2. Enable the SAC function.

    # Enable the security engine.
    <AC6605> system-view
    [AC6605] sysname AC
    [AC] defence engine enable
    NOTE:
    After the security engine is enabled, the system automatically loads the default signature database.
    # Create an SAC profile and bind it to the VAP profile mapping the AP group ap-group1.
    [AC] wlan
    [AC-wlan-view] sac-profile name wlan-sac
    [AC-wlan-sac-prof-wlan-sac] quit
    [AC-wlan-view] vap-profile name wlan-net
    [AC-wlan-vap-prof-wlan-net] sac-profile wlan-sac
    [AC-wlan-vap-prof-wlan-net] quit
    [AC-wlan-view] quit

  3. Configure optimization for voice and video services.

    # Configure optimization for voice and video services on QQ and WeChat.
    NOTE:

    By default, the voice and video traffic awareness and optimization function is enabled.

    [AC] undo voice-aware app-protocol qq disable
    [AC] undo voice-aware app-protocol weixin disable
    [AC] undo video-aware app-protocol qq disable
    [AC] undo video-aware app-protocol weixin disable

    [AC-wlan-rrm-prof-wlan-rrm] undo dynamic-edca enable 
    [AC-wlan-rrm-prof-wlan-rrm] multimedia-air-optimize enable
    [AC-wlan-rrm-prof-wlan-rrm] quit
    
    # Create the 2G radio profile wlan-radio2g and bind the RRM profile wlan-net to it.
    [AC-wlan-view] radio-2g-profile name wlan-radio2g 
    [AC-wlan-radio-2g-prof-wlan-radio2g] rrm-profile wlan-rrm
    [AC-wlan-radio-2g-prof-wlan-radio2g] quit
    # Create the 5G radio profile wlan-radio5g and bind the RRM profile wlan-net to it.
    [AC-wlan-view] radio-5g-profile name wlan-radio5g 
    [AC-wlan-radio-5g-prof-wlan-radio5g] rrm-profile wlan-rrm
    [AC-wlan-radio-5g-prof-wlan-radio5g] quit
    # Bind the 5G radio profile wlan-radio5g and 2G radio profile wlan-radio2g to the AP group ap-group1.
    [AC-wlan-view] ap-group name ap-group1 
    [AC-wlan-ap-group-ap-group1] radio-5g-profile wlan-radio5g radio 1
    Warning: This action may cause service interruption. Continue?[Y/N]y 
    [AC-wlan-ap-group-ap-group1] radio-2g-profile wlan-radio2g radio 0
    Warning: This action may cause service interruption. Continue?[Y/N]y 
    [AC-wlan-ap-group-ap-group1] quit
    [AC-wlan-view] quit

  4. Verify the configuration.

    # If a user makes video calls after optimization is configured for video services and the configuration is successfully delivered, you can run the display video-aware-list command to check video session information.
