Example

vpls 7 customer 1 svc-sap-type any create
            description "Default tls 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

In the above example, all eight FCs are configured and eight meters are configured. In addition, multipoint meter "11" is configured for use. For the VPLS service, four traffic types are identified (unicast and BUM). Because multicast meter "11" is defined, BUM traffic type for all FCs will use meter "11". The number of classification entries required is:

FC (nc) = 1 + 0 + 1 + 0 = 2 FC (h1) = 1 + 0 + 1 + 0 = 2 FC (ef) = 1 + 0 + 1 + 0 = 2 FC (h2) = 1 + 0 + 1 + 0 = 2 FC (l1) = 1 + 0 + 1 + 0 = 2 FC (af) = 1 + 0 + 1 + 0 = 2 FC (l2) = 1 + 0 + 1 + 0 = 2 FC (be) = 1 + 0 + 1 + 0 = 2 FC (default-fc) = 1 + 0 + 1 + 0 = 2

TC = 1*2 (FC-nc) + 1*2 (FC-h1) + 1*2 (FC-ef) + 1*2 (FC-h2) + 1*2 (FC-l1) + 1*2 (FC-af) + 1*2 (FC-l2) + 1*2 (FC-be) + 1*2 (default-fc) = 18

TP = Total meters used is 8.

Hence, in this example num-qos-classifiers is set to (maximum (18, (8*2)) = 18.

If the same policy is attached to an IES or an VPRN service with multicast enabled, then the number of resources required would be 18 (that is, num-qos-classifiers needs to be set to 18). The calculations are the same those for VPLS service (shown above).
