Preparing to Download or Upload a Configuration File By Using TFTP

Before yo u begin downloading or uplo ading a co nfiguration 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
Note You must restart th e inetd daemon after modifyi ng 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

•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 hav e a router to route traf fic 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 op erati ons , ensu re that the pe rmis sion s on the file ar e set co rrec tly. The per mis sion
on the file should be world-read.
