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 on page 301.

For more information about file transfer protocols, consult the following resources:
■ RFC 959—File Transfer Protocol (FTP) (October 1985)
■ RFC 1350—Trivial File Transfer Protocol (TFTP) (Revision 2) (July 1992)
Copying and Redirecting Files
You have two options for copying or redirecting files to or from a remote FTP or
TFTP server:
■ Include all remote file data in the copy command. You can specify remote files
using the URL format and the file redirect option for the related show commands.
■ Use the host command to define the host and the appropriate file transfer
protocol. FTP is the default if you do not specify a file transfer protocol or when
Domain Name System (DNS) service is used to map IP addresses to the hostname.
If you include the remote file data, the copy command contains a source and
destination filename, either of which (but not both) can be remote files. The following
URL format is supported for both source and destination files:
protocol://[username [:password]@]location[/directory]/filename
The location can be a hostname or an IP address.
