Example

*A:dut-a# configure service epipe 7 
*A:dut-a>config>service>epipe# info 
----------------------------------------------
            description "Default epipe for service id 7"
            sap 1/1/3:201 create
                description "Default sap for service id 7"
                ingress
                    qos 23  enable-table-classification
                exit
                egress
                exit
            exit
            no shutdown
----------------------------------------------

In the above example, all eight FCs are configured and eight meters are configured. For Epipe service only unicast traffic-type is identified. This requires one classification entry per FC configured and an additional one for the default-fc assignment, for a total of 9 classification entries.

FC (nc) = 1+ 0+ 0 + 0 = 1 FC (h1) = 1+ 0+ 0 + 0 = 1 FC (ef) = 1+ 0+ 0 + 0 = 1 FC (h2) = 1+ 0+ 0 + 0 = 1 FC (l1) = 1+ 0+ 0 + 0 = 1 FC (af) = 1+ 0+ 0 + 0 = 1 FC (l2) = 1+ 0+ 0 + 0 = 1 FC (be) = 1+ 0+ 0 + 0 = 1 FC (default-fc) = 1+ 0+ 0 + 0 = 1

TC = 1*1 (FC-nc) + 1*1 (FC-h1) + 1*1 (FC-ef) + 1*1 (FC-h2) + 1*1 (FC-l1) + 1*1 (FC-af) + 1*1 (FC-l2) + 1*1 (FC-be) + 1*1 (default-fc) = 9

TP = Total meters used is 8.

Hence, in this example num-qos-classifiers is set to (maximum (9, (8*2)) = 16.

If the same policy was going to be attached to an IES or VPRN SAP without multicast enabled (VPRN example shown below, IES is similar), the num-qos-classifiers required would be the same as that for am Epipe service (that is, 16). The calculations are the same as that for Epipe service.
