tc-tcindex

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 to match packets based on their tcindex field value, i.e. the combination 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  con-
              sulted.

       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.
