Calculating the number of classification entries per FC

Apply the rules (above) to determine the number of classification entries per FC (C_i) (only for the ‟FCs in use”) using the following equation:

C(i) = ∑FC_{i (unicast)} + FC_{i (multicast)} + FC_{i (broadcast)} + FC_{i
(unknown_unicast)}

i = nc, h1, ef, h2, l1, af, l2, be

where:

FC_i (unicast), FC_i (multicast), FC_i (broadcast), and FC_i (unknown-unicast) are set to a value of 1 if the FC uses a classifier to identify traffic-type unicast, multicast, broadcast, and unknown-unicast, respectively
FC_i (unicast), FC_i (multicast), FC_i (broadcast), and FC_i (unknown-unicast) are set to a value of 0 if the FC does not use a classifier to identify the traffic-type

If the user does not configure meters explicitly for the FC and multipoint meter ‟11” is not created, the default unicast meter is used for all traffic types and therefore, only one classification entry in hardware is required by the FC. If the user does not configure meters explicitly for the FC and multicast meter ‟11” is created, the default unicast meter and the default multicast meter are used. Therefore, by default, two classification entries in hardware are required by an FC.
