tc-tcindex (8)
NAME
tcindex - traffic control index filterSYNOPSIS
tc filter ... tcindex [ hash SIZE ] [ mask MASK ] [ shift SHIFT ] [ pas_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 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.
