TRANSFERING FILES AND GENERIC COMMANDS
Various commands are available to transfer files from the router to an external system and vice
versa. The most common are:
scp: transfers files from/to the router via SCP
ftpput: sends a file to a remote system via FTP
ftpget: receives a file from a remote system via FTP
tftp: transfers files from/to the router via TFTP
ftp: enables a FTP interactive session
The syntax of the command is the same as in Linux.
The TFTP protocol has also these two commands:

There are other two commands available:
telnet
ssh
they are used to access the router from a remote system.
