2.
Open the configuration file in a text editor, such as vi or emacs on UNIX or Notepad on a PC.
3.
Extract the portion of the configuration file with the desired commands, and save it in a new file.
4.
Copy the configuration file to the appropriate server location. For example, copy the file to the TFTP directory on the
workstation (usually /tftpboot on a UNIX workstation).
5.
Make sure the permissions on the file are set to world-read.
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. 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.
Ensure that the configuration file to be downloaded is in the correct directory on the TFTP server (usually /tftpboot
on a UNIX workstation).
For download operations, ensure that the permissions on the file are set correctly. The permission on the file should
be world-read.
Before uploading the configuration file, you might need to create an empty file on the TFTP server. To create an
empty file, enter the touch filename command, where filename is the name of the file you will use when uploading
it to the server.
During upload operations, if you are overwriting an existing file (including an empty file, if you had to create one) on
the server, ensure that the permissions on the file are set correctly. Permissions on the file should be world-write.
Downloading the Configuration File By Using TFTP
To configure the switch by using a configuration file downloaded from a TFTP server, follow these steps:
1.
Copy the configuration file to the appropriate TFTP directory on the workstation.
