Example: Simple Shared Shaping for ATM VCs
The following commands configure a simple shared shaper for a VC, as shown in
Figure 18 on page 80. In this example, the best-effort queue for logical interface VC
3 is shaped to a shared rate of 1 Mbps. The voice and video queues for VC 3 share
the 1 Mbps with the best-effort traffic. The voice queue has first claim on the shared
1 Mbps, but only up to its individual shaping rate of 200 Kbps. The video queue
claims up to the next 300 Kbps. The best-effort queue obtains whatever bandwidth
remains of the 1 Mbps after the voice and video traffic have made their claims.
