Command History

Releases	Modifications
Release 2.0	This command was introduced on the Cisco CRS-1.
Release 3.0	No modification.
Release 3.2	This command was first supported on the Cisco XR 12000 Series Router. The command was made available in Administration EXEC mode. Support was added to copy to a designated node or to all nodes. Hardware partition support was added.
Release 3.3.0	No modification.
Release 3.4.0	No modification.

Usage Guidelines

To use this command, you must be in a user group associated with a task group that includes the proper task IDs. For detailed information about user groups and task IDs, see the Configuring AAA Services on Cisco IOS XR Software module of the Cisco IOS XR System Security Configuration Guide.

Source and destination can each be a configuration file, a text file, or a file system. Enter source and destination URL information, usernames, and passwords and issue the copy command. The networking device prompts for any missing information.

The exact format of the source and destination varies according to the file or directory location. Enter the device or network location for the file system type.

To copy a file from a source on the router to a destination on the router, specify a source location node-id and a destination location node-id. To copy the file to all nodes, use the keywords location all.

In the alias syntax for the ftp:, rcp:, and tftp: keywords, the location is either an IP address or a host name. The filename is specified relative to the directory used for file transfers.

When no alias or is specified, the networking device looks for a file in the current directory. To view the current directory, enter the pwd command.

---

Note During processing of the copy command, you might see the "C" character. For all files being copied, "C" indicates that the copy process is taking place. The entire copying process might take several minutes and differs from protocol to protocol and from network to network.

---

Table 1 describes the network protocols supported by the Cisco IOS XR software.

Table 1 Network Protocols Supported by the Cisco IOS XR software 

Prefix	Name	Description
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	Rcp is a protocol that allows users to copy files to and from a file system residing on a remote host or server on the network. Rcp uses TCP to ensure the reliable delivery of data. Rcp downloads require a username.

Additional usage guidelines are in the following sections:

•Invalid Combinations of Source and Destination

•Using TFTP

•Using FTP

•Using rcp

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/crs_software.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.

---

Using FTP

FTP servers require a username and password for each client request. The Cisco IOS XR software sends the first valid username in the following list:

1. The username and password specified in the copy command, if a username is specified.

The syntax is as follows:

copy ftp://username:password@hostname or ipaddress/directory-path/pie-name target-device [location node-id | location all]

Example:
RP/0/RP0/CPU0:router# copy ftp://john:secret@10.1.1.1/images/crs_software.pie disk1:

2. An "anonymous" username and password. The anonymous password is "root@ip address," where "ip address" is the IP address of the local networking device.

3. A password "username@iosname.domain" formed by the networking device. The variable "username" is the username associated with the current session, "iosname" is the configured host name, and "domain" is the domain of the networking device.

The username and password must be associated with an account on the FTP server. If you are writing to the network server, the FTP server must be properly configured to accept the FTP write request from the user on the networking device.

If the network server has a directory structure, the configuration file or image is written to or copied from the directory associated with the username on the network server. For example, if the system image resides in the home directory of a user on the network server, specify the name of that user as the remote username.

Refer to the documentation for your FTP server for more details.

Using rcp

The rcp protocol requires a username upon each request. When you copy a configuration file or image between the networking device and an rcp server, the Cisco IOS XR software sends the first valid username in the following list:

1. The remote username specified in the copy command, if one is specified.

2. The username set by the rcp client username command, if the command is configured.

3. The networking device host name.

For the rcp copy request to process successfully, an account must be defined on the network server for the remote username. If the network administrator of the destination server did not establish an account for the remote username, this command does not run successfully. If the network server has a directory structure, the configuration file or image is written to or copied from the directory associated with the remote username on the network server. For example, if the system image resides in the home directory of a user on the network server, specify the name of that user as the remote username.

If you are writing to the network server, the rcp server must be properly configured to accept the rcp write request from the user on the networking device. For UNIX systems, add an entry to the .rhosts file for the remote user on the rcp server. Suppose the networking device contains the following configuration lines:

hostname Rtr1

ip rcp remote-username User0

If the IP address of the networking device translates to company.com, then the .rhosts file for User0 on the rcp server should contain the following line:

company.com Rtr1

See the documentation for your rcp server for more details.

If you are using a personal computer as a file server, the computer must support remote shell (rsh) protocol.

Table 2 shows the syntax and example for the copy command when used with FTP, rcp, and TFTP network servers.

When flash memory is full, you might need to rearrange the files so that the space used by the files marked "deleted" can be reclaimed. (This "squeeze" process is required for linear flash memory cards to make sectors contiguous; the free memory must be in a "block" to be usable.)

When you enter the squeeze command, the router copies all valid files to the beginning of flash memory and erases all files marked "deleted." After the squeeze process is completed, you can write to the reclaimed flash memory space.

---

Caution After performing the squeeze process you cannot recover deleted files using the undelete command.

---

In addition to removing deleted files, the squeeze command removes any files that the system has marked as "error." An error file is created when a file write fails (for example, the device is full). To remove error files, you must use the squeeze command.

Rewriting flash memory space during the squeeze operation may take several minutes.

For flash file systems, when you delete a file, the Cisco IOS XR software simply marks the file as deleted, but it does not erase the file. The undelete command allows you to recover a "deleted" file on a specified flash memory device. You must undelete a file by its index because you could have multiple deleted files with the same name. For example, the "deleted" list could contain multiple configuration files with the name router-config. You undelete by index to indicate which of the many router-config files from the list to undelete. Use the dir command to learn the index number of the file you want to undelete.

You cannot undelete a file if a valid (undeleted) file with the same name exists. Instead, you first delete the existing file and then undelete the file you want. For example, if you had an undeleted version of the router-config file and you wanted to use a previous, deleted version instead, you could not simply undelete the previous version by index. You would first delete the existing router-config file and then undelete the previous router-config file by index. You can delete and undelete a file up to 15 times.

On flash file systems, if you try to recover the configuration file pointed to by the CONFIG_FILE environment variable, the system prompts you to confirm recovery of the file. This prompt reminds you that the CONFIG_FILE environment variable points to an undeleted file. To permanently delete all files marked "deleted" on a flash memory device, use the squeeze command.
