tcindex - traffic control index filter
] [ classid
This filter allows to match packets based on their
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
- 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
value before use. If a
has been set, masking is done before shifting.
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.
This is the opposite of
and the default. The filter will classify the packet even if there is no class
present for the resulting class ID.
