There are two matching sequences: Configuration order, auto sort: ACL number Acl-number [match-order {config | auto}] Several commands that the H3C ACL applies to an interface: I.

In real-world projects, user groups and access control nodes can be dynamically added! A few things are confusing! 1 ZF put the resources
