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

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

Using the equation, calculate the total classification entries used by this policy, as follows:

TC = (0 * 0)nc + (0 * 0)h1 + (0 * 0)ef + (0 * 0)h2 + (0 * 0)l1 + (1 * 2)af + (1 * 2)l2 + (0 * 0)be = 4

The number of meters used = 2 (because both FCs use meter ‟1” and meter ‟11”).

Hence, in this example num-qos-classifiers 4 is used (that is, maximum of (4, (2 * 2))).

If the same policy were to be used for a SAP in an Epipe service, then because all traffic is classified to a unicast traffic type and because 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 = 0 + 0 + 0 + 0 = 0 FCl1 = 0 + 0 + 0 + 0 = 0 FCaf = 1 + 0 + 0 + 0 = 1 FCl2 = 1 + 0 + 0 + 0 = 1 FCbe = 0 + 0 + 0 + 0 = 0

Using the above equation, calculate the total classification entries used = 2 and meters used = 1.

As can be seen here, for Epipe SAP with the same amount of resources allocated one can have more FCs if need be.
