Let's look at the example of transmitting the traffic of two services traffic transmission associated with vlan id's 161 and 162, between Master and Slave (Figure 17a). Totally the service traffic The total traffic of the services should not exceed 9 Mbps.
The Master's device configuration can be performed in a the following way (Figure 17b):
- Class 16 has been configured with 9 Mbps throughput.
- Class 16 is the parent to of the channels 161 and 162, i.e. the total traffic at these logical channels is limited to 9 Mbps.
- Traffic The traffic with vlan 161 ID 16 is associated with the logical channel 161, ; the traffic of vlan 162 is associated with the logical channel 162.
- The CIR values value for channel 161 is 4 Mbps , and for channel 162 is 5 Mbps. If both services will actively exchange data, the threshold values for their traffic will be equal to the equal CIR for of each channel.
- The MIR values value for channel 161 is 9 Mbps , and for channel 162 it is 7 Mbps. If there is no traffic in the logical channel 162, then the threshold value for channel 161 will be equal to the MIR, i.e. 9 Mbps. Otherwise In the other case when there is no traffic in the logical channel 161, the threshold value for channel 162 will be equal to 7 Mbps.

Recommendations for the throughput limitation configuration
Use the following recommendations during the data throughput limitation configuringconfiguration:
- Traffic The traffic of all network services should be limited. It allows to take control over all traffic flows and consciously separately allocate resources for these flows.
- Throughput The throughput limitation should be performed on the devices closest to the data source. There is no need to duplicate throughput limiting rules for the data flow flows throughout the chain of intermediate devices.
- Many network services are bidirectional, it requires so they require restrictions on devices to for both the incoming and the outgoing traffic.
- To set the correct throughput threshold values, evaluate firstly first the average and the maximum values of the services service traffic. Pay special attention to the most busy hours. Collect Collecting data for analysis is possible via the InfiMONITOR monitoring system.
- The sum of the CIR values sum of the logical channels associated with one class should not exceed the maximum class throughput.
