In example 4, assuming the policy is attached to a SAP in a VPLS service, classification entries used per FC use the following computation.

FCnc = 1 + 1 + 1 + 0 = 3

Because this FC uses unicast, broadcast, and multicast meter, three entries are required to identify these traffic types explicitly. Unknown-unicast traffic type is classified using the same entry as multicast traffic type and uses the same meter.

FCh1 = 1 + 1 + 1 + 1 = 4

Because this FC uses unicast, broadcast, multicast and unknown-unicast meter, four entries are required to identify these traffic types explicitly.

FCef = 1 + 1 + 1 + 0 = 3

FCh2 = 1 + 1 + 1 + 0 = 3

Because this FC uses unicast meter and broadcast meter, two entries are required to identify these traffic types explicitly. Another entry is required to classify multicast and unknown-unicast traffic type to the same FC and use the default meter 11.

FCl1 = 1 + 1 + 1 + 0 = 3

FCaf = 1 + 1 + 1 + 0 = 3

FCl2 = 0 + 0 + 0 + 0 = 0

FCbe = 1 + 0 + 1 + 0 = 2

Using the preceding equation, the total classification entries used = 21 and the total meters used = 8.

If the same policy were used for a SAP in an Epipe service, all traffic is classified to a unicast traffic type and only unicast meters are used, use the following computation.

FCnc = 1 + 0 + 0 + 0 = 1

FCh1 = 1 + 0 + 0 + 0 = 1

FCef = 1 + 0 + 0 + 0 = 1

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 preceding equation, the total classification entries used = 7 and the total meters used = 4.

Using the same policy for Epipe SAP can lead to inefficient use of resources. Nokia recommends creating a different policy with the required number of resources (that is, num-qos-classifiers 16)
