with the logical interface, which in this scenario is the VP. VP-level queuing does not
guarantee fairness to the voice and video traffic for each VC, but fairness is not a major
issue because admission control guarantees that the voice and video queues do not
become congested.
This example assumes the same traffic class and traffic-class group configurations that
are used in "Example: Simple Shared Shaping for ATM VCs" on page 79.

Figure 20: VP Shared Shaping

The following set of commands configures the shared shaper in Figure 20 on page 81.
(config)#scheduler-profile 2mbps
(config-scheduler-profile)#shaping-rate 2000000
(config-scheduler-profile)#exit
(config)#scheduler-profile 400kbps
(config-scheduler-profile)#shaping-rate 400000
(config-scheduler-profile)#exit
(config)#scheduler-profile shared-5mbps
(config-scheduler-profile)#shared-shaping-rate 5000000 simple
(config-scheduler-profile)#exit
(config)#qos-profile vp-subscriber1
(config-qos-profile)#atm-vp node scheduler-profile shared-5mbps
(config-qos-profile)#atm-vp node group AF
(config-qos-profile)#atm-vp node group EF
(config-qos-profile)#atm-vc node
(config-qos-profile)#atm-vc queue traffic-class best-effort scheduler-profile default
(config-qos-profile)#atm-vp queue traffic-class video scheduler-profile 2mbps
(config-qos-profile)#atm-vp queue traffic-class voice scheduler-profile 400kbps
(config-qos-profile)#exit
In this example, the best-effort scheduler node for the VP is shaped to a shared rate of
5 Mbps. The EF and AF queues for the VP share the 5 Mbps with the best-effort traffic.
The EF queue has first claim on the shared 5 Mbps, but only up to its individual shaping
