Configuration File Types and Location

Startup configuration files are used during system startup to configure the software. Running
configuration files contain the current configuration of the software. The two configuration files can be
different. For example, you might want to change the configuration for a short time period rather than
permanently. In this case, you would change the running configuration but not save the configuration by
using the copy running-config startup-config privileged EXEC command.
The running configuration is saved in DRAM; the startup configuration is stored in the NVRAM section
of flash memory.

Creating a Configuration File by Using a Text Editor

When creating a configuration file, you must list commands logically so that the system can respond
appropriately. This is one method of creating a configuration file:
Copy an existing configuration from a WMIC to a server.
Step 1
For more information, see the
page
"Downloading a Configuration File by Using RCP" section on page
Open the configuration file in a text editor such as vi or emacs on UNIX or Notepad on a PC.
Step 2
Extract the portion of the configuration file with the desired commands, and save it in a new file.
Step 3
Copy the configuration file to the appropriate server location. For example, copy the file to the TFTP
Step 4
directory on the workstation (usually /tftpboot on a UNIX workstation).
Make sure the permissions on the file are set to world-read.
Step 5

Copying Configuration Files by Using TFTP

You can configure the WMIC by using configuration files you create, download from another device, or
download from a TFTP server. You can copy (upload) configuration files to a TFTP server for storage.

Preparing to Download or Upload a Configuration File by Using TFTP
Before you begin downloading or uploading a configuration file by using TFTP, perform these tasks:
•

Uploading the Configuration File by Using TFTP, page 7-11
Ensure that the workstation acting as the TFTP server is properly configured. On a Sun workstation,
make sure that the /etc/inetd.conf file contains this line:
tftp dgram udp wait root /usr/etc/in.tftpd in.tftpd -p -s /tftpboot
Make sure that the /etc/services file contains this line:
