Guest Dan Posted August 8, 2008 Posted August 8, 2008 when I ping from machine A to B: >ping 121.1.1.1 -v 0x47 windows keeps delivering the ToS field as 0x46 in the IP datagram. This is what Wireshark reported. However, I didn't have any problem when pinging from a linux box. It appears that the 2nd Hex will always be round off to the lower even number when pinging from windows machine, e.g: 0x27 becomes 0x26 0x15 becomes 0x14 0xA3 becomes 0xA2 and so on.... When looking closely in Wireshark, this is this due to the last bit of the QoS because it's related to ECN-CE ....whatever, this means....does anyone know how can I turn on this function? So I can set the traffic all the way from 0 to 255 without any limitation? and secondly, starting with windows 2000 ....has microsoft updated the QoS filed to DSCP? Because when I look at ping /?, it still showing QoS filed as ToS and eveyrone knows that ToS is obsolete.
