Working with Configuration Files
Make sure that the /etc/services file contains this line:
tftp 69/udp
Note
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.

•
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

Downloading the Configuration File By Using TFTP
To configure the switch by using a configuration file downloaded from a TFTP server, follow these
steps:
steps:
Step 1
Copy the configuration file to the appropriate TFTP directory on the workstation.
Step 2
Verify that the TFTP server is properly configured by referring to the
.
Step 3
Log into the switch through a Telnet session.
Step 4
Download the configuration file from the TFTP server to configure the switch.
Specify the IP address or host name of the TFTP server and the name of the file to download.
Use one of these privileged EXEC commands:
•
copy tftp:[[[//location]/directory]/filename] system:running-config
•
copy tftp:[[[//location]/directory]/filename] nvram:startup-config
The configuration file downloads, and the commands are executed as the file is parsed line-by-line.
This example shows how to configure the software from the file tokyo-confg at IP address 172.16.2.155:
Switch# copy tftp://172.16.2.155/tokyo-confg system:running-config
Configure using tokyo-confg from 172.16.2.155? [confirm] y
Booting tokyo-confg from 172.16.2.155:!!! [OK - 874/16000 bytes]
