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