The DSCP-based Priority page provides fields for defining output queue to specific DSCP fields. When TCP/IP’s TOS/DSCP
mode is applied, the PoE Switch recognizes TCP/IP Differentiated Service Codepoint (DSCP) priority information from the
DS-field defined in RFC2474.
This page provides DSCP-based Priority. The DSCP-based Priority screen in Figure 4-8-5 & Figure 4-8-6 appears.
