       Writing interface or interface4 applies traffic shaping rules only to IPv4 traffic.

       Writing interface6 applies traffic shaping rules only to IPv6 traffic.

       Writing interface46 applies traffic shaping rules to both IPv4 and IPv6 traffic.

       The actual traffic shaping behaviour of  a  class  is  defined  by  adding  classes.   See


              To  achieve  best results with incoming traffic shaping, you should not use 100% of
              the available bandwidth at the interface level.

              If you use all there is, at 100% utilisation of the  link,  the  neighbour  routers
              will  start  queuing  packets.   This  will destroy prioritisation.  Try 85% or 90%


       device This is the interface name as shown by ip link show (e.g. eth0, ppp1, etc.)

       name   This is a single-word name for this interface and is  used  for  retrieving  status
              information later.

              If set to input, traffic coming in to the interface is shaped.

              If set to output, traffic going out via the interface is shaped.

              if  set  to  bidirectional traffic for both input and output can be shaped.  If you
              need to differentiate  input  and  output  parameters  per  statements  within  the
              interface, you can prefix them with input or output like this:

                     interface eth0 lan bidirectional ...
                         class voip input commit 1Mbit output commit 2Mbit ...

              For  a  list of optional class parameters which can be applied to an interface, see

       speed  For an interface, the committed speed must be specified with the rate option.   The
              speed can be expressed in any of the units described in fireqos.conf(5).


       To create an input policy on eth0, capable of delivering up to 1Gbit of traffic:

              interface eth0 lan-in input rate 1Gbit
