Match-all classifier in tc(8) Linux Match-all classifier in tc(8)
matchall - traffic control filter that matches every packet
tc filter ... matchall [ skip_sw | skip_hw ] [ action
ACTION_SPEC ] [ classid CLASSID ]
The matchall filter allows one 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: clsact
tc filter add dev eth1 ingress \
matchall skip_sw \
action mirred egress mirror \
dev eth2
The first command creates a clsact qdisc with handle ffff: on
device eth1 where the second command attaches a matchall filters
on it that mirrors the packets to device eth2 for ingress.
To create egress mirroring from port eth1 to port eth2:
tc qdisc add dev eth1 handle ffff: clsact
tc filter add dev eth1 egress \
matchall skip_sw \
action mirred egress mirror \
dev eth2
The first command creates a clsact qdisc with handle ffff: on
device eth1 where the second command attaches a matchall filters
on it that mirrors the packets to device eth2 for egress.
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
