Resequencing an ACL or Prefix List
Resequencing is available for IPv4 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 increment when using these commands.
• Resequence an IPv4 or MAC ACL.
EXEC mode
resequence access-list {ipv4 | mac} {access-list-name StartingSeqNum Step-to-
Increment}
• Resequence an IPv4 prefix-list.
EXEC mode
resequence prefix-list {ipv4} {prefix-list-name StartingSeqNum Step-to-
Increment}
Example of Resequencing ACLs When Remarks and Rules Have the Same Number
Example of Resequencing ACLs When Remarks and Rules Have 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.
