Resequencing an ACL or Prefix List Resequencing is available for IPv4 ACLs, prefix lists, and MAC ACLs. To resequence an ACL or prefix list, use the appropriate command in Table 5-4. When using these commands, you must specify the list name, starting number, and increment. Table 5-4. Resequencing ACLs and Prefix Lists List IPv4 or MAC ACL IPv4 prefix-list Command Command Mode resequence access-list {ipv4 | mac} {access-list-name StartingSeqNum Exec Step-to-Increment} resequence prefix-list {ipv4} {prefix-list-name StartingSeqNum Step-to-Increment} Exec Figure 5-21 shows the resequencing of an IPv4 access-list beginning with the number 2 and incrementing by 2. Figure 5-21.

Remarks that do not have a corresponding rule are incremented as a rule. These two mechanisms allow remarks to retain their original position in the list. For example, in Figure 5-22, remark 10 corresponds to rule 10 and as such they have the same number before and after the command is entered. Remark 4 is incremented as a rule, and all rules have retained their original positions. Access Control Lists (ACLs) | 91
