Yes, a local netgroup file may be used.  You simply need to create the /etc/netgroup file on the filer.  It might be a good idea to create an /etc/nsswitch.conf file on the filer as well to look something like the following.

-gdg
 

mspadmin1.dal.mslp.ti.com[18]% cat nsswitch.conf
hosts: files    dns
passwd: files   nis
netgroup: files
group: files    nis
shadow: files   nis
mspadmin1.dal.mslp.ti.com[19]%

Hi

Is it possible to use a local netgroup file instead of
the NIS netgroup map on a filer ( ontap 6.1.2R2 ).
I have too much hosts to put in /etc/exports file
