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
configuration is often applied across multiple devices, it is convenient for the network manager to define QoS Policies
(configuration 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
activation 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 configuration
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. Following are the device classes:
• Rapier
• SwitchBlade
• iMAP (Telesyn)
• AT8900
• ATRouter
• iMAP_EPON
• AlliedWare Plus
Since these devices classes share or do not share certain QoS capabilities, care must be taken when defining the QoS
policies.
• 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.
