In an export entry, you can specify that a file or directory be exported to a subnet
instead of individual hosts. The export entry for exporting to subnets can use the
ro , rw , or root option; you cannot specify a subnet in the list for the access
option.
Instead of specifying a host name or netgroup name in the entry, specify the sub-
net in one of the following formats:
dotted
_
IP
/
num
_
bits
The
dotted
_
IP
field is either an IP address or a subnet
number. The
num
_
bits
field specifies the size of the sub-
net by the number of leading bits of the netmask.
”[ network ]
subnet
[ netmask ]
netmask
”
The
subnet
field is the subnet number. The
netmask
field
is the netmask.
In UNIX, it is illegal to export a directory that has an exported ancestor in the
same file system. Data ONTAP 5.3 does not have this restriction. For example,
you can export both the / directory and the /home directory. In determining per-
missions, the filer uses the longest matching prefix.
EXAMPLES
In the following example, all network clients can mount the /home directory but
only the adminhost can mount the / directory:
/ -access=adminhost,root=adminhost
/home
The following examples show different ways of specifying an export entry
that exports the /home directory to the 123.45.67.0 subnet with the
255.255.255.0 netmask:
/home -rw=123.45.67.0/24
/home -rw=123.45.67/24
/home -rw=”network 123.45.67.0 netmask 255.255.255.0”
/home -rw=”123.45.67.0 255.255.255.0”
