Basic Configurations
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 = 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 above equation, to get total classification entries used = 4 and Meters used = 1. As can
be seen here, using the same policy for Epipe SAP can lead to inefficient use of resources. Hence,
it is recommended to create a different policy with the required number of resources (that is,with
num-qos-classifiers 4)
