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:
