Quality of Service
You can configure the Quality of Service to apply different priorities to
traffic on the router. Click on Add to configure network traffic classes.
After you click on the Add button, the following screen appears allowing you
to set up Quality of Service and Differentiated Services configurations by
defining traffic classification rules.
NOTE: The following screen is the default screen where Enable
Differentiated Service Configuration item has not been enabled. If the
checkbox is checked, the screen looks slightly different as shown in the next
screenshot after this one.
