Resequencing An Acl Or Prefix List - Dell Force10 MXL Blade Configuration Manual

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 appropriate command in
name, starting number, and increment.

Figure 5-21 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 continue to have the same sequence
number after the
incremented as a rule. These two mechanisms allow remarks to retain their original position in the list.
For example, in
before and after the command is entered. Remark 4 is incremented as a rule, and all rules have retained
their original positions.
