Limiting Traffic Rate QoS Configuration
26.10.6 Example Configurations
This section includes examples of rate limiting policy configurations.
Per-Flow Rate Limiting
The following is an example of configuring per-flow rate limiting on the RS.
Figure 26-5 Per-flow rate limiting
Traffic from two interfaces, ipclient1 with IP address 1.2.2.2 and ipclient2 with IP address 3.1.1.1, is restricted to 10
Mbps for each flow with the following configuration:
Flow-Aggregate Rate Limiting
In the following example, traffic from the subnetwork 122.132.0.0/16 to the Internet will be rate limited to 256 Kbps
while traffic to the subnetwork will be rate limited to 64 Kbps.
