Channelized Intelligent Queuing Interfaces

In JUNOS software release 5.6 and later, Juniper Networks adds support for enhanced channelized interfaces called channelized intelligent queuing (IQ) interfaces. Formerly known as Channelized Q Performance Processor (QPP) interfaces, the interfaces provide a more flexible way to configure channels than earlier channelized Physical Interface Cards (PICs) and a simplified configuration structure self-contained in the [edit interfaces] hierarchy level. Channelized IQ interfaces also enable class of service at the PIC level rather than the Flexible PIC Concentrator (FPC) level.

This guide highlights the features of the new channelized PICs with intelligent queuing and their similarities to and differences from the original channelized interfaces.
