4.15.3.1 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 4-15-5
