host1(config)#scheduler-profile shared-1mbps
Configure the shared-shaping rate.
2.
host1(config-scheduler-profile)#shared-shaping-rate 128000 burst 32767 simple
host1(config-scheduler-profile)#shared-shaping-rate 80000 + 53000
host1(config-scheduler-profile)#exit
The range for the shared-shaping rate is 1000–100000000 bps (1 Kbps–1000 Kbps);
the default is the minimum shaping rate (1 Kbps).
Use the operator and operandValue variables to specify the shared shaping rate as an
expression.
Use the bps or kbps keywords to specify the unit of the shaping rate. By default, the
shaping rate is configured in bps.
Use the burst keyword to configure the catch-up number associated with the shaper;
the range is 0–522240 (0–510 KB). If you do not specify a burst value, the router
selects an applicable default value.
Use the milliseconds or bytes keywords to specify the unit of the burst size.
You can specify simple to shape data queue rates to the value of the shared rate
minus the combined voice and video traffic rate. By default, shared shaping is set to
auto. In this mode, the router selects the type of shared shaping that is applied
according to the type of line module. Compound shared shaping is
hardware-dependent. If you specify compound for line modules that do not support
it, an error message is generated and the router applies simple shared shaping.
Configure the QoS profile and reference the scheduler profile.

(config-qos-profile)#atm-vc node group EF
(config-qos-profile)#atm-vc queue traffic-class best-effort scheduler-profile
shared-1mbps
(config-qos-profile)#exit
TIP: The scheduler profile that you configured with the shared-shaping
rate must be referenced in the best-effort queue or the best-effort
scheduler node.
Attach the profile to the interface.
