This example configures a WRR-WFQ profile on all ports of the line card in slot 2 and assigns weight
values (1,2,3,4,12,13,14,15) to the physical queues (0 to 7). This example also configures all the
ports to use WFQ QoS algorithm with a maximum rate 50000 kbps.
This example configures a shaping profile, EXAMPLE2. The maximum rate is 50000 kbps for queues
0 to 2 and 75000 kbps for queues 3 to 5. Then it assigns this profile to port 1 of the line card in slot
2. This example also shows the EXAMPLE2 QoS shaping profile's settings. Note that the default
maximum rate of a port is 100000 kbps with a depth of 255 packets.
This example shows how to configure two VC-shaping profiles. One is EXAMPLE-50M with a
maximum rate of 50000 kbps and a depth of 100 packets. The other one is EXAMPLE-75M with a
