Unable to delete an ACL in the running configuration

Attempting to delete an ACL that is currently assigned to an interface removes all configured ACEs from the ACL, but leaves an “empty” ACL in the configuration. To delete an ACL that is currently assigned to an interface, do the following:

Procedure
  1. In the interface context, use the no ipv6 access–group command to remove the ACL from the interface.
  2. Use the no ipv6 access-list <name–str> command to delete the ACL.
