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 switch to a server.
Step 1
For more information, see the
page
"Downloading a Configuration File By Using RCP" section on page
Step 2 Open the configuration file in a text editor, such as vi or emacs on UNIX or Notepad on a PC.
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 switch by using configuration files you create, download from another switch, 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, do these tasks:

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:
tftp 69/udp
You must restart the inetd daemon after modifying the /etc/inetd.conf and /etc/services files.
Note
To restart the daemon, either stop the inetd process and restart it, or enter a fastboot
command (on the SunOS 4.x) or a reboot command (on Solaris 2.x or SunOS 5.x). For more
information on the TFTP daemon, see the documentation for your workstation.
Ensure that the switch has a route to the TFTP server. The switch and the TFTP server must be in
the same subnetwork if you do not have a router to route traffic between subnets. Check connectivity
to the TFTP server by using the ping command.
