In the example above, assuming the policy is attached to a SAP in a VPLS service, the following number of classification entries per FC:

FCnc = 0 + 0 + 0 + 0 = 0 FCh1 = 0 + 0 + 0 + 0 = 0 FCef = 0 + 0 + 0 + 0 = 0 FCh2 = 1 + 0 + 1 + 0 = 2 FCl1 = 1 + 0 + 1 + 0 = 2

Because FCl1 uses unicast meter and multicast meter, an entry is needed to identify these traffic types explicitly. Broadcast and unknown-unicast traffic is also classified using the same entry as multicast and use the same meter.

FCaf = 1 + 0 + 1 + 0 = 2

Because FCaf uses unicast meter, an entry is needed to identify these traffic types explicitly. Another entry is needed to classify broadcast, multicast and unknown-unicast traffic type to the same FC and use the default meter ‟11”.

FCl2 = 0 + 0 + 0 + 0 = 0 FCbe = 1 + 0 + 1 + 0 = 2

Using the above equation, the total classification entries used = 8 and meters used = 4.

If the same policy were to be used for a SAP in an Epipe service, then since all traffic is classified to a unicast traffic type and since only unicast meters are used, the following:

FCnc = 0 + 0 + 0 + 0 = 0 FCh1 = 0 + 0 + 0 + 0 = 0 FCef = 0 + 0 + 0 + 0 = 0 FCh2 = 1 + 0 + 0 + 0 = 1 FCl1 = 1 + 0 + 0 + 0 = 1 FCaf = 1 + 0 + 0 + 0 = 1 FCl2 = 0 + 0 + 0 + 0 = 0 FCbe = 1 + 0 + 0 + 0 = 1

Using the above equation, the total classification entries used = 4 and meters used = 2.
