Resequencing An Acl Or Prefix List - Dell Force10 C150 Configuration Manual

IPv4 and IPv6 ACLs and prefixes and MAC ACLs can be resequenced. No CAM writes happen as a result
of resequencing, so there is no packet loss; the behavior is like Hot-lock ACLs.
Note: ACL Resequencing does not affect the rules or remarks or the order in which they are applied. It
merely renumbers them so that new rules can be placed within the list as desired.
Table 8-3. ACL Resequencing Example (Insert New Rules)
seq 5 permit any host 1.1.1.1
seq 6 permit any host 1.1.1.2
seq 7 permit any host 1.1.1.3
seq 10 permit any host 1.1.1.4
Table 8-4. ACL Resequencing Example (Resequenced)
seq 5 permit any host 1.1.1.1
seq 10 permit any host 1.1.1.2
seq 15 permit any host 1.1.1.3
seq 20 permit any host 1.1.1.4

Resequencing an ACL or Prefix List

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
number, and increment when using these commands.
