6.11 Quality of Service (QoS) Network Management
6.11.1 Overview
Configuring QoS capabilities on the various iMAP device types is fairly detailed and complex. Since the same QoS configu-
ration is often applied across multiple devices, it is convenient for the network manager to define QoS Policies (configura-
tion information) in the NMS and then separately deploy the policies to a specific set of devices and their ports.
The QoS Configuration feature interacts with the Profile Management Feature (see 6.10), particularly with respect to activa-
tion of QoS Policies. The Profile Management Feature manages Port Profiles which include references to the QoS Policies
that are to be associated with a device port.
Note: There are also Device Policies that allow for the setting of switch-wide QoS parameters to a set of
devices.
The following table lists the major areas for configuring traffic management and should help the user find the appropriate
information or task.
6.11.1.1 Overview of Traffic Attributes
The following concepts are used when configuring QoS using the AlliedView NMS. These concepts follow the configura-
tion screens that make up the creation of policies and are usually filled in this order.
Device Class - A class (or set) of the same type of devices. There are six device classes:
Rapier
SwitchBlade
iMAP
AT8900
ATR oute r
iMAP_EPON
Since these devices classes share or do not share certain QoS capabilities, care must be taken when defining the QoS pol-
icies.
QoS Policy Action - A QoS Policy Action is specifically for a Rapier or Switchblade device and involves actions that
apply to all flows on the port.
