QoS Properties

Quality of Service (QoS) prioritizes the traffic flow based on the type of traffic and can be applied to prioritize traffic for latency-sensitive applications (such as voice or video) and to control the impact of latency-insensitive traffic.

To configure QoS properties, follow these steps:

Procedure

Step 1

Click Quality of Service > General > QoS Properties.

Step 2

Set the QoS mode. The following options are available:

  • Disable—QoS is disabled on the device.

  • Basic—QoS is enabled on the device in Basic mode.

  • Advanced—QoS is enabled on the device in Advanced mode.

Step 3

Select Port/LAG and click GO to display/modify all ports/LAGs on the device and their CoS information.

The following fields are displayed for all ports/LAGs:

  • Interface—Type of interface.

  • Default CoS—Default VPT value for incoming packets that do not have a VLAN Tag. The default CoS is 0.

Step 4

Click Apply. The Running Configuration file is updated.

To set QoS on an interface, select it, and click Edit.

Step 5

Enter the parameters.

  • Interface—Select the port or LAG.

  • Default CoS—Select the default CoS (Class-of-Service) value to be assigned for incoming packets (that do not have a VLAN tag).

Step 6

Click Apply. The interface default CoS value is saved to Running Configuration file.

To restore the default CoS values, click Restore CoS Defaults.
