Match-all classifier in tc(8)                 Linux                 Match-all classifier in tc(8)



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 fil-
              ter, or TC offload is not enabled for the interface, 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 sec-
       ond 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
