2020-07-17 07:56:38 +0000 | marked best answer | What capture filter will test whether the DSCP value in the IPv4 header is in a particular range? Hello, I just want to capture traffic with specific DSCP Value Range. How can I achieve this? Is there a way to filter for an value range or mask? I did find the following in the wireshark blog: ip[1] & 0xfc == 0xb8 This one works, but only for DSCP Value 46. I want to capture only packets with DSCP Value Range 8-23... I tried it with an edited mask and filter value, but this does not work, only the last original filter for EF...: ip[1] & 0xe0 == 0x20 or ip[1] & 0xe0 == 0x40 or ip[1] & 0x80 == 0xb8 or ip[1] & 0xfc == 0xb8 So can anyone help me? Kind regards Robert PS: OS Windows 10 Enterprise x64 1909 18363.959 Wireshark Version 3.2.5 (v3.2.5-0-ged20ddea8138) |
