6.1 ACL
6.1.1 Introduction
Access Control List (ACL) is a set of ordered rules, which can control the A10E/A28E to
receive or discard some data packet, thus eliminate impact of invalid packets on the network.
You need to configure rules in network to control illegal packets influent network
performance and decide packets allowed passing. These rules are defined by ACL.
ACL is a series of rule composed of permit | deny sentences. The rules are described
according to source address, destination address, port ID of data packets. The device judges
whether to receive or discard packets according to the rules.
