IPF on Solaris 10 prior 10 8/07 releases

I'm trying to enable IPF ( ip filter ) on solaris 10 release 6/06

 Solaris 10 6/06 s10s_u2wos_09a SPARC

so i enabled

svc:/network/ipfilter:default

it was disabled by default and

svc:/network/pfil:default

was enabled and online

there only one config file under etc

$/etc/ipf/ipf.conf

i followed the following docs which suggests

a now i'm confused i can't find the

/etc/ipf/pfil.ap 

file
what's wrong or what i'm missing .
any suggestions.
Thanks
