z You can only modify the existing rules of an ACL that uses the rule order of config. When
modifying a rule of such an ACL, you may choose to change just some of the settings, in which
case the other settings remain the same.
z You cannot create a rule with, or modify a rule to have, the same permit/deny statement as an
existing rule in the ACL.
z When the ACL rule order is auto, a newly created rule will be inserted among the existing rules in
the depth-first order. Note that the IDs of the rules still remain the same.
z You can modify the rule order of an IPv6 ACL with the acl ipv6 number acl6-number [ name
acl6-name ] match-order { auto | config } command, but only when the ACL does not contain any
rules.
z The rule specified in the rule comment command must already exist.
