NOTE: ACL resequencing does not affect the rules, remarks, or order in which they are applied. Resequencing merelyrenumbers the rules so that you can place new rules within the list as needed.Table 10. ACL ResequencingRules ResquencingRules Before Resequencing: seq 5 permit any host 1.1.1.1seq 6 permit any host 1.1.1.2seq 7 permit any host 1.1.1.3seq 10 permit any host 1.1.1.4Rules After Resequencing: seq 5 permit any host 1.1.1.1seq 10 permit any host 1.1.1.2seq 15 permit any host 1.1.1.3seq 20 permit any host 1.1.1.4Resequencing an ACL or Prefix ListResequencing 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 incrementwhen using these commands.• IPv4, IPv6, or MAC ACLEXEC moderesequence access-list {ipv4 | ipv6 | mac} {access-list-name StartingSeqNum Step-to-Increment}• IPv4 or IPv6 prefix-listEXEC moderesequence prefix-list {ipv4 | ipv6} {prefix-list-name StartingSeqNum Step-to-Increment}Examples of Resequencing ACLs When Remarks and Rules Have the Same Number or Different NumbersRemarks and rules that originally have the same sequence number have the same sequence number after you apply theresequence command.The example shows the resequencing of an IPv4 access-list beginning with the number 2 and incrementing by 2.Dell(config-ext-nacl)# show config!ip access-list extended testremark 4 XYZremark 5 this remark corresponds to permit any host 1.1.1.1seq 5 permit ip any host 1.1.1.1remark 9 ABCremark 10 this remark corresponds to permit ip any host 1.1.1.2seq 10 permit ip any host 1.1.1.2seq 15 permit ip any host 1.1.1.3seq 20 permit ip any host 1.1.1.4Dell# endDell# resequence access-list ipv4 test 2 2Dell# show running-config acl!ip access-list extended testremark 2 XYZremark 4 this remark corresponds to permit any host 1.1.1.1seq 4 permit ip any host 1.1.1.1remark 6 this remark has no corresponding ruleAccess Control Lists (ACLs) 133
