FTOS Configuration Guide for the C-Series - Force10 Networks

Resequencing is available for IPv4 and IPv6 ACLs and prefix lists and MAC ACLs. To resequence an
ACL or prefix list use the appropriate command in Table 36. You must specify the list name, starting
number, and increment when using these commands.
Table 36 Resequencing ACLs and Prefix Lists
List Command Command Mode
IPv4, IPv6, or MAC ACL resequence access-list {ipv4 | ipv6 | mac} {access-list-name
StartingSeqNum Step-to-Increment}
IPv4 or IPv6 prefix-list resequence prefix-list {ipv4 | ipv6} {prefix-list-name
StartingSeqNum Step-to-Increment}
Figure 242 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
the resequence command is applied. Remarks that do not have a corresponding rule will be incremented
as as a rule. These two mechanisms allow remarks to retain their original position in the list.
