Overview

Network Queue QoS Policy Queue Parenting

A network-queue policy only supports direct port parent priority association. Intermediate
schedulers are not supported on network ports or channels.
Egress Port Scheduler Overrides
Once a port scheduler has been associated with an egress port, it is possible to override the
following parameters:
The orphan priority level (level 1) has no configuration parameters and cannot be overridden.
Applying a Port Scheduler Policy to a Virtual Port
In order to represent a downstream network aggregation node in the local node scheduling
hierarchy, a new scheduling node, referred to as virtual port, and vport in CLI have been
introduced. The vport operates exactly like a port scheduler except multiple vport objects can
be configured on the egress context of an Ethernet port.
This feature applies to the 7450 ESS and 7750 SR only.
