ACL and rule limits

There are SW limits to the number of ACLs and rules supported.

The following software limits apply to ACL names:
  • An ACL name must be unique, 1 through 63 characters long, and must begin with a–z, A–Z or 0–9. You can also use underscore (_) or hyphen (-) in an ACL name, but not as the first character.
  • Rule sequence numbers can range from 1 through 65535.

The following table displays the maximum numbers of ACLs and ACL rules that you can define on a device.
