5.8.13.2 Class Creation
If you want to set up QoS for your local network, click New. The overview shows previously config-
ured QoS settings. To edit a QoS setting, click on the respective pencil icon at the end of the over-
view. .
The new screen dialog Edit Classes for Data Traffic allows you to create or edit QoS classes. To do this,
select the DSCP class from one of the following four main categories:
BE

Best Effort Forwarding.
AFxy

Assured Forwarding enables the transmission of four independent classes. Within a class, IP
packets can be assigned one of three different, assured priority levels.
CSx

The "Class selector (CS)" settings are used for IP priorities (IP Precedence) of the older Type of
Service (ToS) QoS to ensure backward compatibility.
EF

Expedited Forwarding is intended to provide low delay, low jitter and low loss in the delivery of
packets.
Once you have selected the desired DSCP class, you can pre-assign a certain percentage of the total
available bandwidth to it. Select the option Allow More to allow this value to be exceeded if needed.
Click Activate to enable the selected DSCP class. Click Save to save your settings and return to the
QoS Overview.
For the configured DSCP classes to take effect, select the option Enable QoS and click Save.
