However, IOS 12.3 introduces the Sequence ACL feature, which allows you to edit ACLs in-place on your IOS device. in a Sequence ACL, you can insert and delete statements and comments.In a sequence ACL, each ACL statement has a unique sequence number. By default, the sequence number starts at 10, and the increment is also 10o To determine whether the IOS device supports sequence ACLs, use the command show access-lists to display the ACLs, if the ACL statement is preceded by a sequence number, the IOS device supports sequence ACLoRouter# show access-listsExtended IP access list 10110 permit ip host 192.168.101.69 any20 permit ip host 192.168.101.89 anyAs you can see from this example, ACL101 uses a sequence number. The sequence number may be added when the router boots up and loads the ACL, or it may be added when you create or modify the ACL in the CLI or Cisco Configuration Professional ( CP). When you save an IOS configuration to NVRAM, the sequence number is not stored with the ACL statement: Cisco does this for backward compatibility with older IOS versions that do not support sequence ACLs.The Sequence ACL feature can be used for both Named ACLs and Numbered ACLs, but to edit Numbered ACLs, you must process them in the same way as Named ACLs. Once you enter ACL sub-naming mode, you can use no and the sequence number to remove the corresponding statement.
