Mechanism for ACL rules on S series switches to take effect

ACL rules on S series switches are classified into the following two modes:
An ACL is bound to the traffic policy and delivered to the hardware of the LPU through the first mode.
The second mode relates to software processing. An ACL prevents users from logging in through Telnet. After being sent to the CPU, packets are processed in the sequence that is specified during the configuration of the ACL. Rules in an ACL can be matched according to the depth first principle or the configuration order.
