Adding a NIS Domain
4-6 CLI Storage-Management Guide
Updating the NIS Database
The ARX keeps an internal copy of all the NIS netgroups and their fully-resolved
hosts. The database is built when you add the NIS domain to the switch; it is used for
switch operation as well as the show commands above. To avoid excessive traffic to
the DNS server, the switch does not update this database automatically. You can
rebuild the database manually after any large-scale DNS or NIS changes.
From priv-exec mode, use the
nis update command to update the netgroup database:
nis update [nis-domain]
where nis-domain (optional: 1-256 characters) causes the update to focus on a
single NIS domain.
In a redundant pair of switches, this triggers concurrent NIS updates from both peers.
Since they keep independent NIS caches, failovers do not incur any additional
downtime for NIS.
The
show nis domain command (above) shows the time of the most-recent update.
For example, the following command sequence updates all NIS domains:
bstnA6k(gbl)# end
bstnA6k# nis update
bstnA6k# ...
Reading the Update Report
Each NIS update creates one or more reports (one per updated domain) to show its
results. The NIS software names the reports according to the following convention:
nis-update.domain-name.rpt
where domain-name is the name of the NIS domain in the report.
To conserve disk space, each NIS update overwrites any previous reports.
Use the
show reports command to list all reports, including the NIS-update reports.
