Abstract:
Systems and methods for allocating a per-interface access control list (ACL) counter are disclosed. An ACL is applied to a data packet received at an interface of the network element. In response to matching the highest priority ACL rule, a counter value is obtained based on a combination of a base index and an expansion index value. The base index, expansion index, and counter values are stored in their respective tables. The counter value is uniquely associated with the specific ACL rule hit and the interface used to receive the data packet. Systems and methods also allocate a next set of expansion and counter tables when their storage capacity is exceeded. When the next set of tables are allocated, the older set of tables along with their index mappings and entries are preserved.
