Chapter 12 QoS Configuration
Traffic over-subscription is a common cause for the instability of network links; if many links
in the mesh network is over-subscribed, the performance of the overall network becomes
unstable. In order to avoid over-subscribing any individual WDS link, we strongly
recommend enabling QoS to control and limit the traffic flows injected into the network.
This
chapter contains information on defining and configuring QoS on MSR2000.

Enable/Disable QoS Service
By default, QoS doesn’t take effect on MSR2000. Use the following commands to start
or stop the QoS in CONFIGURATION mode.

Enable QoS, start QoS service and all
QoS classes attached to WDS
interface will take effect
Disable QoS, stop QoS service and
all QoS classes attached to WDS
interface will be disabled
When enable QoS globally, user should attach QoS to WDS Interface. There are two
kinds of WDS interfaces, ManualWDS interface created by users and AutoWDS
interface created by RF-Management service. Correspondingly, for ManualWDS
interface, user should manually configure QoS settings. On the other hand, for AutoWDS
interface, it will automatically configure QoS settings if QoS service is enabled.
Configuring QoS over ManualWDS Interface
There are two steps to run QoS service over one ManualWDS interface: creating one
QoS class and attaching it to ManualWDS interface. First, user should configure one
QoS class which specifies the maximal and minimal bandwidth of this ManualWDS
interface. After creating one specific QoS class, user should attach this QoS class to
ManualWDS interface.
