Apply the rules to determine the number of classification entries per FC (only for the FCs in use)
using the following equation:
C(i)=ΣFCi(unicast)+FCi(multicast)+FCi(broadcast)+FCi(unknown_unicast)
i=nc,h1,ef,h2,l1,af,l2,be
where FCi (unicast), FCi (multicast), FCi (broadcast), and FCi (unknown-unicast) are set to a
value of 1 if this FC uses classifier to identify traffic-type unicast, multicast, broadcast and
unknown-unicast respectively. FCi (unicast), FCi (multicast), FCi (broadcast), and FCi (unknown-
unicast) are set to a value of 0 if this FC does not use a classifier to identify this traffic-type.
If the user does not configure meters explicitly for the FC and 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 meter "11" is
created, the default unicast meter and multicast meter are used. Therefore by default, two
classification entries in hardware are required by a FC.
Taking into account the number of match criteria and the number of FCs used, use the equation
given below to arrive at total number of classification entries per policy, for example:

If a FC is in use and is created without explicit meters, use default meter #1 for unicast
traffic and for multicast traffic. This requires one classification entry in hardware. This
assumes default multipoint meter #11 is not created by the user.
If a FC is in use and is created without explicit meters, use default meter #1 for unicast
traffic and default meter #11 (assuming meter "11" is created by the user), for multicast
traffic. This requires two classification entries in hardware.
If a FC is in use and is created with an explicit unicast meter, use that meter for unicast
traffic and for multicast traffic. This requires one classification entries in hardware. This
assumes default multipoint meter "11" is not created by the user.
If a FC is in use and is created with an explicit unicast meter, use that meter for unicast
traffic and use default meter #11 (assuming meter "11" is created by the user) for multicast
traffic. This requires two classification entries in hardware.
If a FC is in use and is created with an explicit unicast meter and explicit multicast meter,
use the unicast meter for unicast traffic and multicast meter for multicast traffic. This
requires two classification entries in hardware.
