The TCPDUMP filter to match a DSCP is a little tricky to construct. I need to explain how the filter works and also what TCPDUMP sees in the ToS Byte of the IP header and then how to filter on just the DiffServ extensions.
FIRST THE ANSWER:
(in case it is not important to understand how the filter is constructed)
– an example filtering on DSCP decimal 20 (AF22):
tcpdump -i eth0 (ip and (ip[1] & 0xfc) >> 2 == 20) -vvv
– An example filtering on DSCP Hex 14 (also decimal 20 or AF22):
tcpdump -i eth0 (ip and (ip[1] & 0xfc) >> 2 == 0x14) –vvv
