Defining Classes of Service
It is only necessary to adjust the classes of service if the SIP server, PBX, or handsets are using a DSCP tag
to CoS (Class of Service) mapping that is not already defined in the Enterasys controller. The defined
mapping in the Enterasys controller is shown in the table below.

• The defaults for the 80xx phones for class of service and DSCP tags depend on the Telephony Type
selected from the Admin menus. They are Voice (Premium – class 6) 46 and Video (Gold (4)) – 40
or 26. This values work with the default values in the Enterasys.
• The defaults for the 8400 Series phones for class of service and DSCP tags are Voice (Premium –
class 6) 46 and Video (Gold (4)) – 44. 44 does not work properly for prioritizing the control frames
with the default of the Enterasys. Configurations can be used to set the 8400 Series phones to a
different DSCP value. This can be achieved using the phone web browser on a phone by phone
basis. Here is a screen shot of the setting, reached as Settings from the top menu->Network-
>QoS.
