Resequencing an ACL or Prex List
Resequencing is available for IPv4 and IPv6 ACLs, prex lists, and MAC ACLs.
To resequence an ACL or prex list, use the following commands. You must specify the list name, starting number, and increment when
using these commands.
• IPv4, IPv6, or MAC ACL
EXEC mode
resequence access-list {ipv4 | ipv6 | mac} {access-list-name StartingSeqNum Step-to-Increment}
• IPv4 or IPv6 prex-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 Dierent 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.
