Basic Configurations
Since 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. Additionally note that meter 11 is not defined to be
multipoint meter, but is used as a normal unicast meter.
FCl2 = 0 + 0 + 0 + 0 = 0
FCbe = 1 + 1 + 1 + 0 = 3
Since this FC uses unicast, broadcast and multicast meter, three entries are needed 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. Additionally note that meter 11 is not defined to be multipoint
meter, but is used as a normal unicast meter.
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 + (50 * 3)af + (0 * 0)l2 + (1 * 3)be =
153
The number of meters used in this policy = 4. Hence, in this example num-qos-classifiers 154 is
used (maximum of (153, (2 * 4)) = 153, rounded off to the next multiple of 2 will be 154).
Hence, in this example num-qos-classifiers 154 is used (maximum of (153, (2 * 4)) = 153, rounded
off to the next multiple of 2 will be 154).
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 = 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
Using the equation, calcuate 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 + (50 * 1)af + (0 * 0)l2 + (1 * 1)be =
51
The number of meters used in this policy = 2.
Hence for Epipe SAP it is recommended to define another sap-ingress policy with num-qos-
classifiers 52 is used (that is, maximum of (51, (2 * 2)) = 51, rounded off to the multiple of 2 will
be 52).
