z When the ACL match order is auto, a newly created rule will be inserted among the existing rules
in the depth-first match order. Note that the IDs of the rules still remain the same.
You can modify the match order of an ACL with the acl number acl-number [ name acl-name ]
match-order { auto | config } command but only when it does not contain any rules.
