фильтр контроля трафика fwmark (fwmark traffic control filter)
Имя (Name)
fw - fwmark traffic control filter
Синопсис (Synopsis)
tc filter ... fw [ classid CLASSID ] [ action ACTION_SPEC ]
Описание (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 filter 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 classification 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.
Параметры (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.
Примеры (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
