Hi All

I am trying to use Windows Ping Command to TAG ICMP with the Binary value of 101 in the Precedance 3 bit feild . This is using the -v TOS command suffix on ping.

The command I understand is ping xxx.xxx.xxx.xxx -v 160

This result in the following packet

Interface Rx: v=LAN1 LAN
Ethernet Header info - dst=00e007009f53 src=00123f12dd32 len=60
IP Header info - Dst=200.0.0.205 Src=200.0.0.92 vl=0x45 tos=0x00 len=42 id=0xb77d
ttl=128 flg=0x00 off=0x0000 pcol=17(UDP) sum=0xf21b
UDP Header info - DstPort=50794(IPO Monitor) SrcPort=4099 Len=22 Sum=0x9824

TOS feild is still marked as tos=0x00 or 000

How does the -v command work exaclty Microsoft TECH NET is no help and only provides the follwoing

-v TOS : Specifies the value of the Type of Service (TOS) field in the IP header for Echo Request messages sent. The default is 0. TOS is specified as a decimal value from 0 to 255. ?????

I have also tried the following

ping xxx.xxx.xxx.xxx -v 101
ping xxx.xxx.xxx.xxx -v 5

HELP !!!!!!
