NAME
matchall - traffic control filter that matches every packet SYNOPSIS
tc filter ... matchall [ skip_sw | skip_hw ] [ action ACTION_SPEC ] [ classid CLASSID ] DESCRIPTION
The matchall filter allows to classify every packet that flows on the port and run a action on it. 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. 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 inter- face, operation will fail. skip_hw Do not process filter by hardware. EXAMPLES
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 SEE ALSO
