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.

seq

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.
