Traffic shaping

The terms Class of Service (CoS) and QoS are used in the following context:

CoS provides varying Layer 2 traffic services. CoS refers to classifying traffic into traffic classes, where each class is handled as an aggregate whole, with no per-flow settings. CoS is usually related to the 802.1p service that classifies flows according to their Layer 2 priority, as set in the VLAN header.

QoS refers to Layer 2 traffic and above. QoS handles per-flow settings, even within a single traffic class.

The QoS configuration options are CoS Settings, Queue Settings, DSCP Settings, and Basic Mode.

QoS > CoS Settings

The CoS Settings screen is used to enable or disable CoS.

QoS > CoS Settings

CoS Settings

QoS Mode  Indicates if QoS is enabled. The possible values are:

Disable  Disables QoS.

Basic  Enables QoS. This is the default value.

Class of Service  Specifies the CoS priority tag values, where 0 is the lowest and 7 is the highest.

Queue  Defines the traffic forwarding queue to which the CoS priority is mapped. Four traffic priority queues are supported.

Click Restore Defaults to restore the device factory defaults for mapping CoS values to a forwarding queue.

CoS Default

Unit No.  The unit to which the CoS configuration applies.

Default CoS  Determines the default CoS value for incoming packets for which a VLAN tag is not defined. The possible field values are 0-7. The default CoS is 0.

LAG  The LAG to which the port belongs, if relevant. If the port is a member of a LAG, the LAG settings override the port settings.

Click Save Settings to save the changes, or Cancel Changes to cancel the changes.

QoS > Queue Settings

The Queue Settings screen is used to define the QoS queue forwarding types.

QoS > Queue Settings

Strict Priority  Indicates that traffic scheduling for the selected queue is based strictly on the queue priority.

WRR  Indicates that traffic scheduling for the selected queue is based strictly on the WRR.

Queue  Displays the queue (1-4) for which the queue settings are displayed.

WRR Weight  Displays the WRR weights to queues.

%of WRR Bandwidth  Displays the percentage of bandwidth assigned to the queue. These values are fixed and cannot be modified.

Click Save Settings to save the changes, or Cancel Changes to cancel the changes.
