Configuring ACL

1.1 Overview

The rapid growth of network size and traffic brings challenges to network security and

bandwidth allocation. Packet filtering can help prevent unauthorized access behaviors, limit

network traffic and improve bandwidth use.

ACL (Access Control List) filters traffic as it passes through a switch, and permits or denies

packets crossing specified interfaces or VLANs. It accurately identifies and processes the

packets based on the ACL rules. In this way, ACL ensures security and high service quality

of networks.

ACL helps to:

 Prevent various network attacks, such as attacks caused by IP (Internet Protocol) and

TCP (Transmission Control Protocol).

 Manage network access behaviors, such as controlling access to a network or to

specific resources in your network.

1.2 Supported Features

An ACL takes effect after it is directly bound to an interface or VLAN. After ACL binding, the

packets that match a permit rule or deny rule will be forwarded or discarded.

Policy Binding

An ACL also takes effect when it is applied to a policy which is bound to an interface

or VLAN. After policy binding, the packets that match a permit rule or deny rule will be

forwarded or discarded.
