In example 2, 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 = 1 + 1 + 1 + 0 = 3

FC uses unicast meter and broadcast meter, so 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 + 1 + 1 + 0 = 2

Using this equation, the total classification entries used = 11 (three explicit match criteria entries map to each of FC H2, L1, and AF along with a default classification rule for BE).

Meters used = 3 (FCs use only meter 2, meter 3, and meter 11).

Therefore, in this example, num-qos-classifiers 16 is used (that is, a maximum of (12, (2*3))). Note that the system internally uses 18, instead of 16.

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 = 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 this equation, the total classification entries used = 4 and the total meters used = 1.
