4.9.3.1 TOS/DSCP Configuration
The TOS/DSCP page provides fields for defining output queue to specific DSCP fields. When TCP/IP’s TOS/DSCP mode is
applied, the Managed Switch recognizes TCP/IP Differentiated Service Codepoint (DSCP) priority information from the
DS-field defined in RFC2474.
Enable TOS/DSCP for traffic classification and then the DSCP to priority mapping column is configurable, as the Figure
4-9-5 shows:
Figure 4-9-5: QoS Configuration – TOS Priority
The page includes the following fields:

value.

The values of the IP DSCP header field within the incoming packet.
0~63.
