Examples of Resequencing ACLs When Remarks and Rules Have the Same Number or have Dierent Numbers
Remarks and rules that originally have the same sequence number have the same sequence number after you apply the
resequence 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 test
remark
4 XYZ
remark 5 this remark corresponds to permit 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 20 permit ip any host 1.1.1.4

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.

Route Maps
Similar to ACLs and prex lists, route maps are composed of a series of commands that contain a matching criterion and an action;
however, route maps can change the packets meeting the criterion. ACLs and prex lists can only drop or forward the packet or
