In example 5, assuming the policy is attached to a SAP in a VPLS service, classification entries used per FC use the following computation.

FCnc = 0 + 0 + 0 + 0 = 0

FCh1 = 0 + 0 + 0 + 0 = 0

FCef = 0 + 0 + 0 + 0 = 0

FCh2 = 0 + 0 + 0 + 0 = 0

FCl1 = 0 + 0 + 0 + 0 = 0

FCaf = 1 + 0 + 1 + 0 = 3

Because this FC uses unicast meter, an entry is required to identify these traffic types explicitly. Another entry is required 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 + 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.

Calculate the total classification entries used by this policy using the following equation.

TC = (0 * 0)nc + (0 * 0)h1 + (0 * 0)ef + (0 * 0)h2 + (0 * 0)l1 + (15 * 3)af + (0 * 0)l2 + (1 * 3)be = 48

The total meters used in this policy = 4.

In example 5, num-qos-classifiers 72 is used (that is, a maximum of (48, (2 * 4)) = 48, rounded off to the next available numQosClassifier range.

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 = 0 + 0 + 0 + 0 = 0

FCh1 = 0 + 0 + 0 + 0 = 0

FCef = 0 + 0 + 0 + 0 = 0

FCh2 = 0 + 0 + 0 + 0 = 0

FCl1 = 0 + 0 + 0 + 0 = 0

FCaf = 1 + 0 + 0 + 0 = 1

FCl2 = 0 + 0 + 0 + 0 = 0

FCbe = 1 + 0 + 0 + 0 = 1

Calculate the total classification entries used by this policy using the following equation.

TC = (0 * 0)nc + (0 * 0)h1 + (0 * 0)ef + (0 * 0)h2 + (0 * 0)l1 + (15 * 1)af + (0 * 0)l2 + (1 * 1)be = 16

The total meters used in this policy = 2.

For Epipe SAP, Nokia recommends defining another sap-ingress policy using num-qos-classifiers 16 (maximum of (16, (2 * 2)) = 16.
