Traffic control index filter(8)                 Linux                Traffic control index filter(8)

NAME
       tcindex - traffic control index filter

SYNOPSIS
       tc  filter ... tcindex [ hash SIZE ] [ mask MASK ] [ shift SHIFT ] [ pass_on | fall_through ]
               [ classid CLASSID ] [ action ACTION_SPEC ]

DESCRIPTION
       This filter allows one to match packets based on their tcindex field value, i.e. the combina‐
       tion of the DSCP and ECN fields as present in IPv4 and IPv6 headers.

OPTIONS
       action ACTION_SPEC
              Apply an action from the generic actions framework on matching packets.

       classid CLASSID
              Push matching packets into the class identified by CLASSID.

       hash SIZE
              Hash table size in entries to use. Defaults to 64.

       mask MASK
              An optional bitmask to binary AND to the packet's tcindex field before use.

       shift SHIFT
              The number of bits to right-shift a packet's tcindex value before use. If a  mask  has
              been set, masking is done before shifting.

       pass_on
              If this flag is set, failure to find a class for the resulting ID will make the filter
              fail and lead to the next filter being consulted.

       fall_through
              This  is  the opposite of pass_on and the default. The filter will classify the packet
              even if there is no class present for the resulting class ID.
