You can only modify the existing rules of an ACL that uses the match 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.

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 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 IPv6 ACL with the acl ipv6 number acl6-number [ name
acl6-name ] match-order { auto | config } command but only when it does not contain any rules.
