4.1.4.6 ACL
ACL (Access Control List) is for flow identification. For filtering the packet, the network device
needs to configure a series of matching conditions to classify the packets. The conditions can
be the source address, destination address, and the port number of the packet.
When the device port receives the packet, it can analyze the packet field according to the ACL
rule of the current port. And after the specific packet is identified, the packet is allowed or
forbidden to pass according the preset rule.
