IP ACLs ensure that only authorized users have access to specific resources and block any unwarranted attempts to reach network resources. The following rules apply to IP ACLs: • The 7300 Series Managed Switch does not support IP ACL configuration for IP packet fragments. • The maximum number of ACLs you can create is 100, regardless of type. • The maximum number of rules per IP ACL is hardware dependent. • If you configure a MAC ACL on an interface, you cannot configure an IP ACL on the same interface. • Wildcard masking for ACLs operates differently from a subnet mask. A wildcard mask is in essence the inverse of a subnet mask. With a subnet mask, the mask has ones (1's) in the bit positions that are used for the network address, and has zeros (0's) for the bit positions that are not used. In contrast, a wildcard mask has (0's) in a bit position that must be checked. A '1' in a bit position of the ACL mask indicates the corresponding bit can be ignored. 13-32 Quality of Service (QoS) Commands v1.0, December 2005
