zfilterd - A daemon to use the filter hardware of the OpenArchitect switch for filtering based 
on iptables(8) rules.

zfilterd [-d <level>] [-p <port>] [-f] [-l] [-i <pid>] [-o <pid>] 

zfilterd is a daemon that intercepts filtering rules entered by the user, using iptables(8), 
checks them for validity and then prepares messages for the traffic management daemon ztmd, 
which is responsible for setting up the switch hardware for the filtering rules and actions.

-d <level> Sets the level of debugging output required by 
zconfig. The default level is one (1). Setting the debug level 

higher produces more output. Four (4) is currently the maximum 
output level.

-p <port> Set the multicast port to which messages will be sent.

-f

Run zfilterd in the foreground, by default, it runs in the 

background.

-l

Log all diagnostic output to /var/log/zfilterd.log.

-I <pid>

Set our pid used in identifying ourselves to ztmd

-o <pid>

with.
