TRENDnet TEG-S4000I Switch User Manual


 
Priority 2
Each port can parse the header of an incoming IPv4 header and
identify the Type-Of-Service byte (TOS field). This is extremely
important with the deployment of Microsoft Windows 2000 and the
emerging DiffServ standard, which marks Voice-Over-IP and other
real-time traffic using this field. This feature provides Quality of
Service (QoS).
IF this function of a port is enabled, then the most significant 6 bits of
the TOS (these 6 bits are also known as the DiffServ Code Point
"DSCP" field, value from 0 to 63) are used to assign a priority to the
packet received from this port. Please check the corresponding
mapping checkbox to assign a high priority or uncheck that to assign
a low priority. The old 48310 and 48320 modules do not support this
function.
