Preparing for NFS Authentication
You can create NFS access lists that filter clients based on their IP addresses. You can
enter IP addresses directly and/or refer to pre-defined netgroups at a Network
Information Service (NIS) server. A NIS netgroup defines a group of host machines,
and may also contain other NIS netgroups.
This chapter pertains to NFS-client authentication only; you can skip this chapter
unless you plan to offer NFS service with some level of client authentication.
Before You Begin
A NIS netgroup often refers to hosts by their DNS hostnames rather than their IP
addresses. The ARX must use the local DNS server(s) to translate those names into IP
addresses. Before you start configuring NIS domains, configure the switch to perform
DNS lookups. Refer to the CLI Network-Management Guide: see “Configuring DNS
Lookups” on page 4-35.
All NIS servers used by the switch must also use the same DNS server(s). If this
switch has a redundant peer, it must also use the same DNS server(s).
Adding a NIS Domain
The first step in using NIS netgroups is configuring a NIS domain on the switch. You
can skip to the next section (“Adding an NFS Access List” on page 4-9) if you do not
plan to use any NIS netgroups in your NFS access lists.
