DSCP (Differentiated Services Code Point)
NOTE: DSCP applies to a DM-NVX-36x(C) device that is operating as a transmitter.
To implement Quality of Service (QoS), IP networks use the DSCP value. Within an
IP packet header, the DSCP defines a value from 0 to 63 that maps to a certain traffic
classification. Based on IT department policies, DSCP values are used within a network
to determine the treatment of packets in router queues, the routes of traffic flows, and
per-hop behavior. By default, DSCP is set to 32.
NOTE: Change the DSCP default setting of 32 only if required by IT department policies.
To configure DSCP:
1. Click the Settings tab and then click Stream.
2. In the Advanced section:
a. Disable Auto Initiation by setting the Auto Initiation toggle switch in the Off
(left) position.
b. Stop the stream by clicking Stop.
c. Enable Custom DSCP by setting the Custom DSCP toggle switch in the On
(right) position.
d. In the DSCP text box, enter the desired DSCP value (0 to 63).
e. Enable Auto Initiation by setting the Auto Initiation toggle switch in the On
(right) position. The stream automatically restarts.
NOTE: Disabling DSCP returns the DSCP value to the default setting.
