Juniper JUNOSE 11.1.X - QUALITY OF SERVICE CONFIGURATION GUIDE 3-21-2010, Configuration Manual

Page: 79 / 398

NOTE: For E Series ASIC modules, strict priority is supported only for a single first-level
scheduler node.
When determining the shaping rate, the system includes all bytes in Layer 2
encapsulations. The packets that are included in the rate depend on the Layer 2 node
that is specified in the QoS profile. For example, the shaping rate for an Ethernet
node includes bytes from the Ethernet and VLAN encapsulations.

Configuring a Scheduler Hierarchy
When you configure a scheduler hierarchy, you configure the scheduler profile and
assign attributes.
To configure a scheduler hierarchy:
1.
Configure a scheduler profile.
See “Configuring a Scheduler Profile for a Scheduler Node or Queue” on page 48.
2.
(Optional) Configure attributes in the scheduler profile.
