The na utility provides the commands for managing the Model 5390 server. These commands allow

Set and display the operating characteristics of the Model 5390 server and its ports.

Reboot or reset the Model 5390 server and its ports.

Broadcast administrative messages to the Model 5390 ports.

The Model 5390 server stores the parameters set using na in nonvolatile memory. After a reboot

or a reset, the Model 5390 server updates its run-time parameters with the nonvolatile parameters

changed by na. The na utility can communicate with the Model 5390 server only when the

Model 5390 server is running its operational code.

All na commands are taken from the na standard input: you can run na interactively or provide it

with input through a file or pipeline. You can create a script file containing na commands to

configure the Model 5390 server. This script file can save the configuration information for a specific

Model 5390 server and, when required, restore the configuration.

This chapter illustrates command names, parameter names, and keywords in their long forms.

Examples of na commands sometimes appear without the interactive command prompt, and with

embedded comments that describe the functions being performed. This format resembles the

appearance of na scripts; the portion of the script entered at the terminal in response to the command

prompt appears in bold type.

NOTE: The na utility is stored on and accessed from a UNIX host.
