Setting QoS Properties

To select the QoS mode:

1. Click Quality of Service > General > QoS Properties.
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.
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. The default is only relevant for untagged frames and only if the system is in Basic mode and Trust CoS is selected in the Global Settings page.

Select Restore Defaults to restore the factory CoS default setting for this interface.

4. Click Apply. The Running Configuration file is updated.

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