Basic Configurations
Since this FC uses unicast meter and broadcast meter, two entries are needed to identify these
traffic types explicitly. Another entry is needed 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
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.
FCl2 = 0 + 0 + 0 + 0 = 0
FCbe = 1 + 0 + 1 + 0 = 2
Using the above equation, the total classification entries used = 21 and meters used = 8.
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 = 1 + 0 + 0 + 0 = 1
FCh1 = 1 + 0 + 0 + 0 = 1
FCef = 1 + 0 + 0 + 0 = 1
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, the total classification entries used = 7 and meters used = 4.
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 (i.e.
with
num-qos-classifiers 8
