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:
•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
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, refer to the documentation for your workstation.
•Ensure that the access point has a route to the TFTP server. The access point 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 access point by using a configuration file downloaded from a TFTP server, follow these
steps:
Step1 Copy the configuration file to the appropriate TFTP directory on the workstation.
Step2 Verify that the TFTP server is properly configured by referring to the “Preparing to Download or Upload
a Configuration File by Using TFTP” section on page20-10.
Step3 Log into the access point through a Telnet session.
Step4 Download the configuration file from the TFTP server to configure the access point.
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
