www.dell.com | support.dell.com 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 Table 8-5. You must specify the list name, starting number, and increment when using these commands. Table 8-5. 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} Exec IPv4 or IPv6 prefix-list resequence prefix-list {ipv4 | ipv6} {prefix-list-name StartingSeqNum Exec Step-to-Increment} Figure 8-19 shows the resequencing of an IPv4 access-list beginning with the number 2 and incrementing by 2. 158 | IP Access Control Lists (ACL), Prefix Lists, and Route-maps
