NAME

       basic - basic traffic control filter

SYNOPSIS

       tc filter ... basic [ match EMATCH_TREE ] [ action ACTION_SPEC ] [ classid CLASSID ]

DESCRIPTION

       The basic filter allows to classify packets using the extended match infrastructure.

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.

       match EMATCH_TREE
	      Match  packets  using  the  extended  match  infrastructure.  See  tc-ematch(8)  for a detailed description of the allowed syntax in
	      EMATCH_TREE.

NAME

       fw - fwmark traffic control filter

SYNOPSIS

       tc filter ... fw [ classid CLASSID ] [ action ACTION_SPEC ]

DESCRIPTION

       the fw filter allows to classify packets based on a previously set fwmark by iptables.  If it is identical to the filter's handle, the fil-
       ter matches.  iptables allows to mark single packets with the MARK target, or whole connections using CONNMARK.  The benefit of using  this
       filter  instead of doing the heavy-lifting with tc itself is that on one hand it might be convenient to keep packet filtering and classifi-
       cation in one place, possibly having to match a packet just once, and on the other users familiar with iptables but not tc will have a less
       hard time adding QoS to their setups.

OPTIONS

       classid CLASSID
              Push matching packets to the class identified by CLASSID.

       action ACTION_SPEC
              Apply an action from the generic actions framework on matching packets.

EXAMPLES

       Take e.g. the following tc filter statement:

              tc filter add ... handle 6 fw classid 1:1

       will match if the packet's fwmark value is 6.  This is a sample iptables statement marking packets coming in on eth0:

              iptables -t mangle -A PREROUTING -i eth0 -j MARK --set-mark 6
