the second table. In the same example, apply resequencing if more than two rules must be placed between rules 7 and 10. You can resequence IPv4 and IPv6 ACLs, prefixes, and MAC ACLs. No CAM writes happen as a result of resequencing, so there is no packet loss; the behavior is similar Hot-lock ACLs. NOTE: ACL resequencing does not affect the rules, remarks, or order in which they are applied. Resequencing merely renumbers the rules so that you can place new rules within the list as needed. Table 7. ACL Resequencing Rules Resquencing Rules Before Resequencing: seq 5 permit any host 1.1.1.1 seq 6 permit any host 1.1.1.2 seq 7 permit any host 1.1.1.3 seq 10 permit any host 1.1.1.4 Rules After Resequencing: seq 5 permit any host 1.1.1.1 seq 10 permit any host 1.1.1.2 seq 15 permit any host 1.1.1.3 seq 20 permit any host 1.1.1.4 Resequencing an ACL or Prefix List Resequencing is available for IPv4 and IPv6 ACLs, prefix lists, and MAC ACLs. To resequence an ACL or prefix list, use the following commands. You must specify the list name, starting number, and increment when using these commands. • IPv4, IPv6, or MAC ACL EXEC mode resequence access-list {ipv4 | ipv6 | mac} {access-list-name StartingSeqNum Step-to-Increment} • IPv4 or IPv6 prefix-list EXEC mode resequence prefix-list {ipv4 | ipv6} {prefix-list-name StartingSeqNum Stepto-Increment} Examples of Resequencing ACLs When Remarks and Rules Have the Same Number or Different Numbers The example shows the resequencing of an IPv4 access-list beginning with the number 2 and incrementing by 2. Remarks and rules that originally have the same sequence number have the same sequence number after you apply the resequence command. The following example shows resequencing ACLs when the remarks and rules have the same number. Dell(config-ext-nacl)# show config ! ip access-list extended test 142 Access Control Lists (ACLs)
