matchall - traffic control filter that matches every packet
tc filter ... matchall [ skip_sw | skip_hw ] [ action ACTION_SPEC ]
[ classid CLASSID ]
The matchall filter allows to classify every packet that flows on the
port and run a action on it.
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.
skip_sw
Do not process filter by software. If hardware has no offload
support for this filter, or TC offload is not enabled for the
interface, operation will fail.
skip_hw
Do not process filter by hardware.
To create ingress mirroring from port eth1 to port eth2:
tc qdisc add dev eth1 handle ffff: ingress
tc filter add dev eth1 parent ffff: \
matchall skip_sw \
action mirred egress mirror \
dev eth2
The first command creats an ingress qdisc with handle ffff: on device
eth1 where the second command attaches a matchall filters on it that
mirrors the packets to device eth2.
To create egress mirroring from port eth1 to port eth2:
tc qdisc add dev eth1 handle 1: root prio
tc filter add dev eth1 parent 1: \
matchall skip_sw \
action mirred egress mirror \
dev eth2
The first command creats an egress qdisc with handle 1: that replaces
the root qdisc on device eth1 where the second command attaches a
matchall filters on it that mirrors the packets to device eth2.
To sample one of every 100 packets flowing into interface eth0 to
psample group 12:
tc qdisc add dev eth0 handle ffff: ingress
tc filter add dev eth0 parent ffff: matchall \
action sample rate 100 group 12
