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
