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 one 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.
