Therefore if you need to mark packages for external platforms, you need to set class_order=1 and use the following table to get the correspondence between DSCP values and traffic classes in HTB. If you do not need to mark packages, then it is more convenient to use intuitive correspondence: dscp cs0 text/html 2024-09-26T15:29:43+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.vasexperts.ru/doku.php?id=en:dpi:dpi_options:opt_priority:priority_config&rev=1727364583&do=diff Assigning priorities according to the protocols The protocol priorities (assigned by system administrator) are loaded by DPI from the file /etc/dpi/protocols.dscp. This file is created in two steps: first one creates a text file with the list of protocols and their priorities.
