tcindex - traffic control index filter tc " " filter " ... " tcindex " [ " hash SIZE " ] [ " mask MASK " ] [ " shift SHIFT " ] [ " pass_on " | " fall_through " ] [ " classid CLASSID " ] [ " action ACTION_SPEC " ]" 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.

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.
