The CLASSIFY target can be used to classify packets in such a
way that can be used by a couple of different qdiscs (Queue Disciplines). For
example, atm, cbq, dsmark, pfifo_fast, htb and the prio qdiscs. For more
information about qdiscs and traffic controlling, visit the Linux Advanced Routing
and Traffic Control HOW-TO webpage.
The CLASSIFY target is only valid in the
POSTROUTING chain of the
mangle table.
Table 11-1. CLASSIFY target options
Option | --set-class |
Example | iptables -t mangle -A POSTROUTING -p tcp --dport 80 -j
CLASSIFY --set-class 20:10
|
Explanation | The CLASSIFY target only takes one argument, the
--set-class. This tells the target how to class the packet.
The class takes 2 values separated by a coma sign, like this MAJOR:MINOR. Once
again, if you want more information on this, check the Linux Advanced Routing
and Traffic Control HOW-TO webpage.
