Overview

This section describes the definition and functions of ACL.

Definition

An Access Control List (ACL) is composed of a list of rules. ACL rules classify packets so that the device processes classified packets in different manners.

Purpose

Devices need to communicate with each other on stable networks with reliable data transmission. Example:

  • Defend against various network attacks, such as Internet Protocol (IP), Transmission Control Protocol (TCP), and Internet Control Message Protocol (ICMP) packet attacks.
  • Control network access. For example, control the access of enterprise network users to external networks, specific network resources that users can access, and time ranges in which users can access networks.
  • Limit network traffic and improve network performance. For example, limit bandwidth for upstream and downstream traffic, charge for the bandwidth that users have applied for, and make full use of high-bandwidth network resources.

The ACL solves the preceding problems and ensures stability and reliability of network transmission.
