File Transfer Overview

You may need to transfer files between the following locations:

You can transfer files in any of three ways: the copy command, the system’s FTP server, or a remote host that is configured as an FTP or a Trivial File Transfer Protocol (TFTP) server. See Types of Files Transferred Using the copy Command for the types of files that you can transfer between the locations using the copy command, which activates a hidden FTP or TFTP client on the E Series router.

You can use the system’s FTP server to transfer files between a network host and the user space. When a firewall separates the E Series router from the network host, you must use the FTP server to transfer files to the user space. You can then install the files from the user space to the system space by using the copy command. However, if there is no firewall between the E Series router and the network host, you can use the copy command, the remote FTP server, or the remote TFTP server to transfer files.

For example, you can transfer a file from a network host to an E Series router through FTP, and then transfer the file through the copy command from the E Series router to other E Series routers. See Figure 22.
