I'm not following you when you say "implicit deny". If you remove the actual line where you apply the ACL to an interface, it will permit all traffic. Then you can go make changes to the ACL and re-apply.<br>

I already do this. But with implicit deny there is a brief interruption of traffic. Is there a way to avoid this?

I'm open for ideas on how to accomplish basic adds to a deny list and
