7.2 EXAMPLE 2: SPQ WITH SHAPING
We send 2 Streams (Stream0, Stream1) from PORT-1 to PORT-2. Both Streams each have 100 Mbps. Stream0 includes VLAN
Priority0, Stream1 includes VLAN Priority7. Stream 3 and Stream 4 are only for learning to prevent the traffic from flooding.
Expected Result:
We expect that PORT-2 only can receive 20 Mbps of Stream1 ad 80 Mps of Stream2. This explains how SPQ works on the switch.
