Configuring ACL ACL 1 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), TCP (Transmission Control Protocol), and ICMP (Internet Control Message Protocol) packets. Manage network access behaviors, such as controlling access to a network or to specific resources in your network. 1.2 Supported Features ACL Binding 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. Configuration Guide 365
