ACL and rule limits

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.

Table 1. ACL and rule software limits

IPv6	2048	2048	102400

Maximum of 6K ACL tables can be created per device (2K of MAC-ACL, 2K of IPv4-ACL and 2K of IPv6-ACL).
Maximum of 300K rules can be configured per device (100K rules of MAC-ACL, 100K rules of IPv4-ACL and 100K rules of IPv6-ACL).
