The monitoring screen indicates that all packets are green. The movie is
transmitting at around 1.5 Mbps and CIR = 5 Mbps so all the packets are green
and forwarding.

Since the movie transmits at around 1.5 Mbps and CIR = 1 Mbps and
EIR = 2 Mbps using a 22 Mbps uplink, all yellow packets are forwarded as well.

Since the movie transmits at around 1.5 Mbps using CIR=1 Mbps and
EIR=200 Kbps, 300 Kbps worth of bandwidth is lacking and therefore the
equivalent amount of red packets is dropped.
³ To test the bandwidth profiles for the SHDSL interface at various rates:
1. Navigate to Configuration>QoS>Ingress BW Profiles and select
BW_for_Service_777.
2. Click <Change>.
The Change Ingress BW Profiles window appears (
Figure 4-27 ).
3. Set the CIR to 5000 Kbps and the EIR to 3000 Kbps.
