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.
