Switch commands
Enter the following commands from the switch command line, replacing xx.xx.xx.xx with the TFTP server’s IP
address. Replace <filename1> with the name of the compressed file. Replace <filename2> with the name of
the decompressed file (which automatically unzips during the copy):
console#copy tftp
://xx.xx.xx.xx/<filename1> application <filename1>
console#configure
console(config)#application install <filename2> start-on-boot
console(config)#exit
console#write
The last command, write, copies the running configuration to the startup configuration. The running
configuration must be saved to the startup configuration for the start-on-boot feature to work. The script will
run the next time the switch boots and every time thereafter. There are several ways a script can terminate,
most of which are listed in Section 1.4, Python script flow on Dell N-Series
.
