Configure the traffic classes and traffic-class groups.
See “Configuring Traffic Classes That Define Service Levels” on page 14 and
“Configuring Traffic-Class Groups That Define Service Levels” on page 15.
To configure implicit constituents:
1.
Create the scheduler profile.
host1(config)# scheduler-profile implicit
2.
Configure the shared shaper.
To configure a simple shared shaper:
host1(config-scheduler-profile)# shared-shaping-rate 128000 bps
To configure a compound shared shaper:
host1(config-scheduler-profile)# shared-shaping-rate 128000 burst 32767
compound
3.
(Optional) For compound shared shapers, specify the attributes for the constituent.
host1(config-scheduler-profile)# shared-shaping-constituent weight 28
Including this command does not affect how the system selects the compound
implicit constituent. If the command is present for a constituent that was implicitly
selected, the software configures that constituent using the strict-priority or
weight attributes.
After you configure implicit constituents:
■
Configure the scheduler hierarchy with the best-effort nodes and queues.
See “Configuring a QoS Profile” on page 132.

Explicit Constituent Selection Overview
If you want only a subset of the queues for a subscriber to be shaped to the shared
rate, then you must explicitly identify the desired constituents rather than accepting
the implicitly selected constituents.
