Configuring QoS QoS Defaults
OmniSwitch AOS Release 7 Network Configuration Guide June 2013 page 25-35
Queue Management Defaults
The queue management and related QoS functions are implemented using a Queue Set (QSet) framework.
Each port and link aggregate is associated with a set of eight egress queues, referred to as a Queue Set
Instance (QSI). Each QSI is associated with QSet profile 1 (QSP 1) by default. The default QSP 1 imports
a default Weighted Random Early Detection (WRED) profile (WRP 1).
A QSP defines both global parameters for the profile and individual queue profile parameters that are
applied to the eight queues associated with the QSet instance. See “Congestion Management” on
page 25-10 for more information.
