Traffic Profile

Traffic Profile


In a traffic profile, you can configure priority mapping on the wireless side, air interface performance optimization, traffic policing, and ACL-based packet filtering. The configurations in a traffic profile take effect only after it is bound to a VAP profile.

  • Priority mapping

    Packets of different types have different priorities. For example, 802.11 packets sent by STAs carry user priorities or DSCP priorities, VLAN packets on wired networks carry 802.1p priorities, and IP packets carry DSCP priorities. Priority mapping must be configured on network devices to retain the priorities of packets that traverse different networks.

  • Traffic policing

    To protect network resources and prevent network congestion, you can configure traffic policing to limit the rate of traffic entering a WLAN. In a traffic profile, you can configure rate limiting for upstream and downstream packets of all STAs or each STA on a VAP.

  • Traffic optimization

    On a WLAN, a large number of wireless packets need to be forwarded, which may easily cause network congestion and degrade network performance. WLAN traffic optimization measures, such as traffic limit and multicast optimization, can be taken to adjust network traffic in real time, significantly reducing impact of burst data on the network and improving network performance.

  • ACL-based packet priority re-marking

    You can configure ACL-based packet filtering to enable a device to permit or deny packets matching ACL rules to control network traffic.

  • ACL-based packet priority re-marking

    You can configure ACL-based packet re-marking priorities of packets matching ACL rules to implement differentiated services for wireless packets.
