Report on packet filter statistics and filter list
ipfstat [-6aAfghIinosv] [-d device]
Neutrino
- -6
 
- Display filter lists for IPv6, if available.
 
- -a
 
- Display  the  accounting filter list and show bytes counted against each rule.
 
- -A
 
- Display packet authentication statistics.
 
- -d device
 
- Use a device other than  /dev/ipl  for  interfacing
with the TCP/IP stack.
 
- -f 
 
- Show  fragment  state  information (statistics) and
held state information (in the TCP/IP stack),   if  any.
 
- -g 
 
- Show  groups  currently configured (both active and
inactive).
 
- -h
 
- Show the number of times each one scores a
"hit".  Use in combination with -i.
 
- -i 
 
- Display  the filter list used for the input side of
the TCP/IP stack IP processing.
 
- -I
 
- Swap between retrieving "inactive" or "active"  filter
list details.  Use in combination with -i.
 
- -n
 
- Show  the  "number"  for  each  rule as it is
printed.
 
- -o
 
- Display the filter list used for the output side of the kernel IP
processing.
 
- -s
 
- Show packet/flow state information (statistics only).
 
- -sl
 
- Show held state information (in the TCP/IP stack) if  any (no statistics).
 
The ipfstat utility  displays current TCP/IP stack statistics gathered 
as a result of applying the filters in place
(if  any) to packets going in and out of the TCP/IP stack.  This
is the default operation when no command-line  parameters
are present.
When  used with either -i or -o option, it retrieves and
displays the appropriate list  of  filter  rules  currently
installed and in use by the TCP/IP stack.
