ACL Resequencing
ACL resequencing allows you to re-number the rules and remarks in an access or prex list.
The placement of rules within the list is critical because packets are matched against rules in sequential order. To order new rules using the
current numbering scheme, use resequencing whenever there is no opportunity.
For example, the following table contains some rules that are numbered in increments of 1. You cannot place new rules between these
packets, so apply resequencing to create numbering space, as shown in the second table. In the same example, apply resequencing if more
than two rules must be placed between rules 7 and 10.
