Changing an IP ACL
You can add and remove rules in an existing IPv4 or IPv6 ACL, but you cannot change existing rules. Instead,
to change a rule, you can remove it and recreate it with the desired changes.
If you need to add more rules between existing rules than the current sequence numbering allows, you can
use the resequence command to reassign sequence numbers.
Before you begin
We recommend that you perform ACL configuration using the Session Manager. This feature allows you to
verify ACL configuration and confirm that the resources required by the configuration are available prior to
committing them to the running configuration. This feature is especially useful for ACLs that include more
than about 1000 rules.
