Introduction to ACL
As network scale and network traffic are increasingly growing, network security and bandwidth
allocation become more and more critical to network management. Packet filtering can be used to
efficiently prevent illegal users from accessing networks and to control network traffic and save
network resources. Access control lists (ACL) are often used to filter packets with configured matching
rules.
