Operation Manual – QoS-QoS ProfileH3C S3100 Series Ethernet Switches Chapter 1 QoS Configuration1-16z Large amount of broadcast/multicast packets and large burst traffic exist.z Packets of high-rate links are forwarded to low-rate links or packets of multiplelinks with the equal rates are forwarded to a single link that is of the same rate asthat of the incoming links.Although the burst function helps reduce the packet loss ratio and improve packetprocessing capability in the networks mentioned above, it may affect QoS performance.So, use this function with caution.1.3.10 Traffic MirroringTraffic mirroring identifies traffic using ACLs and duplicates the matched packets to thedestination port.
