Preface
The H3C S7500E documentation set includes 12 configuration guides, which describe the software
features for the H3C S7500E Series Ethernet Switches and guide you through the software
configuration procedures. These configuration guides also provide configuration examples to help you
apply software features to different network scenarios.
The ACL and QoS Configuration Guide describes fundamentals and configuration of ACL and QoS. It
describes how to create IPv4 ACL and IPv6 ACL, use QoS polices to control traffic, and configure
common QoS techniques such as traffic policing, traffic shaping, congestion management, and
congestion avoidance.
