•
Invalid Combinations of Source and Destination
Some combinations of source and destination are invalid. Specifically, you cannot copy the following:
•
From a running configuration to a running configuration
•
From a network device to a network device (for example,
copy ftp: rcp:
)
Using TFTP
TFTP is a simplified version of FTP that allows files to be transferred from one computer to another over
a network, usually without the use of client authentication (for example, username and password).
The syntax is as follows:
copy tftp://
hostname
|
ipaddress
/
directory-path
/
pie-name
target-device
[
location
node-id
|
location
all
]
Example:
RP/0/RP0/CPU0:router#
copy tftp://1.1.1.1/images/casr14k-mcast-p.pie disk1:
Note
Some Cisco IOS XR software images may be larger than 32 MB, and the TFTP services provided by
some vendors may not support a file this large. If you do not have access to a TFTP server that supports
files larger than 32 MB, download the software image using FTP or rcp as described in the following
sections.

tftp:
Trivial File Transfer
Protocol
TFTP is a simplified version of FTP that allows files to be
transferred from one computer to another over a network,
usually without the use of client authentication (for
example, username and password).
ftp:
File Transfer Protocol
FTP is an application protocol, part of the TCP/IP
protocol stack, and is used for transferring files between
network nodes. FTP requires a username and password.
rcp:
Remote Copy Protocol
The rcp protocol allows users to copy files to and from a
file system residing on a remote host or server on the
network. The rcp protocol uses TCP to ensure the reliable
delivery of data. The rcp protocol downloads require a
username.
