Operation Manual – ACLH3C S5600 Series Ethernet Switches Chapter 1 ACL Configuration1-10z If you do not specify the rule-id argument when creating an ACL rule, the rule willbe numbered automatically. If the ACL has no rules, the rule is numbered 0;otherwise, the number of the rule will be the greatest rule number plus one. If thecurrent greatest rule number is 65534, however, the system will display an errormessage and you need to specify a number for the rule.z The content of a modified or created rule cannot be identical with the content ofany existing rules; otherwise the rule modification or creation will fail, and thesystem prompts that the rule already exists.III.

Configuration prerequisitesTo configure a time range-based user-defined ACL rule, you need to define thecorresponding time ranges first. For information about time range configuration, refer toConfiguring Time Range.II. Configuration procedureFollow these steps to define a user-defined ACL rule:To do... Use the command...
