• 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 Step-

to-Increment}

Examples of Resequencing ACLs When Remarks and Rules Have the Same Number or have Different

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

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.

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
