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 one 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 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: 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
