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 Step-toIncrement} 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 remark 4 XYZ remark 5 this remark corresponds to permit any host 1.1.1.1 seq 5 permit ip any host 1.1.1.1 remark 9 ABC remark 10 this remark corresponds to permit ip any host 1.1.1.2 seq 10 permit ip any host 1.1.1.2 seq 15 permit ip any host 1.1.1.3 seq 20 permit ip any host 1.1.1.4 Dell# end Dell# resequence access-list ipv4 test 2 2 Dell# show running-config acl ! ip access-list extended test remark 2 XYZ remark 4 this remark corresponds to permit any host 1.1.1.1 seq 4 permit ip any host 1.1.1.1 remark 6 this remark has no corresponding rule remark 8 this remark corresponds to permit ip any host 1.1.1.2 seq 8 permit ip any host 1.1.1.2 seq 10 permit ip any host 1.1.1.3 seq 12 permit ip any host 1.1.1.4 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. The following example shows remark 10 corresponding 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.
