File System Commands

This chapter describes the Cisco IOS XR software commands used to manage file systems on your router.

Note


The commands in this module should not be used to access or modify any Cisco IOS XR software or configuration files. Use only the documented commands for installing and configuring the router. Modifying, deleting, or moving configuration or software package files using the manual commands described in this module is not required and can result in router downtime, loss of service, and a corrupted database.


cd

To change the current working directory, use cd command in EXEC mode or XR EXEC mode.

cd filesystem:

Syntax Description

filesystem :

(Optional) Location of the new working directory. Include the file system alias for the filesystem argument, followed by a colon and optionally, the name of a directory.

Command Default

The default file directory is disk0:/usr.

Command Modes

EXEC

XR EXEC

Command History

Release

Modification

Release 7.0.1

This command was introduced.

Usage Guidelines

The current working directory is the directory used when EXEC commands that have an optional argument are entered without that argument. Use cd command to define the working directory. For example, when the dir command is entered without specifying the filesystem argument, the files in the current working directory are displayed.

Use cd command without an argument to set the working directory back to the default directory, disk0:/usr.

Examples

The following example shows how to change the current working directory to the root directory on the hard disk. In this example, the pwd command confirms that the working directory has changed to the root directory on the hard disk.


RP/0/RP0/CPU0:router# cd harddisk:
RP/0/RP0/CPU0:router# pwd
		
harddisk:
				

The following example shows how to change the current working directory to the default file directory by specifying the cd command without a location. In this example, the pwd command confirms that the working directory has changed to the default file directory.


RP/0/RP0/CPU0:router# cd
RP/0/RP0/CPU0:router# pwd
		
disk0:/usr
		

cfs check

To clear any inconsistencies between running configuration and binary startup configuration maintained on the disk use cfs check command in XR EXEC mode.

cfs check

Syntax Description

This command has no keywords or arguments.

Command Default

No default behavior or values.

Command Modes

XR EXEC mode

Command History

Release

Modification

Release 3.5.0

This command was introduced.

Release 24.2.1

This command was modified to increase the commit count from 20 to 40.

Usage Guidelines

Use this command to clear any inconsistencies between running configuration and binary startup configuration maintained on the disk.

On executing this command the existing binary startup configuration maintained on the disk will be discarded and the entire binary startup configuration will be recreated from system's running configuration. This will clear any inconsistency between the two.


Note


While this command runs, redundancy of the designated shelf controller (DSC) is disabled.



Note


Executing this command will take a lock to the configuration database, which will prevent any commit operation until this operation completes.

clear configuration ascii inconsistency

To perform an ASCII backup of the system's running configuration and to clear inconsistencies between running configuration and ASCII backup copy maintained on the disk, use the clear configuration ascii inconsistency command in XR EXEC mode.

clear configuration ascii inconsistency

Syntax Description

This command has no keywords or arguments.

Command Default

No default behavior or values.

Command Modes

XR EXEC mode

Command History

Release

Modification

Release 6.5.1

This command was introduced.

Release 24.2.1

This command was modified to include resetting the ASCII backup timer.

Usage Guidelines

Use this command to perform a forced ASCIl backup and reset the periodic ASCII backup timer. Once the backup is complete, the router will automatically initiate the next periodic ASCII backup operation only after 55 minutes from the time the clear configuration ascii inconsistency command is executed.

On executing this command, the ASCII backup will synchronize with the latest running configuration up to the point of the last commit made before executing the command. This clears any inconsistencies between the running configuration and the ASCII backup copy stored on disk. Additionally, this command will reset the periodic ASCII backup timer.

copy

To copy a file from a source (such as a network server) to a destination (such as a flash disk), use copy command in EXEC or Admin EXEC mode.

copy source {location node-id destination location {node-id | all} | running-config [atomic]}

Syntax Description

source

Filename including the directory path or network location of the file. The possible sources are:

directory-path —Directory path of the file from which the file is copied.

access-list { ipv4 | ipv6 }—Copies an access list (EXEC mode only).

apphost: —Copy from apphost: file system

config: —Copy from config: file system

disk0: —Copies from disk0: file system.

disk1: —Copies from disk1: file system.

ftp: —Copies from an FTP network server. The syntax is ftp:[[[//username [:password]@] location]/directory]/filename.

harddisk: —Copies from the hard disk drive file system (if present).

http: —Copy from http: file system

https: —Copy from https: file system

nvram: —Copies from the NVRAM file system.

prefix-list {ipv4 | ipv6} —Copies from a prefix list (EXEC mode only).

roofs: — Copy from rootfs: file system

running-config —Copies from the current system configuration.

tftp: —Copies from a TFTP network server. The syntax is tftp:[[//location]/directory]/filename

xml-schema —Copies the XML schema files as a tar ball file (.tar.gz) [EXEC mode only].

sftp: —Copies from an SFTP network server. The syntax is sftp:[[[//username [:password]@] location]/directory]/filename.

Admin EXEC mode.

Command History

Release

Modification

Release 7.10.1

This command was modified to support public key authentication.

Release 7.9.1

This command was modified to support SFTP and SCP options.

Release 7.0.12

This command was introduced.

Usage Guidelines

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 arguments vary according to the file or directory location. Enter the device or network location for the file system type.

Filenames can include the following characters:

! # $ % & ' + 0 1 2 3 4 5 6 7 8 9 ; @ A B C D E F G H I J K L M N O P Q R S T U V W X Y Z [ ] ^ _ a b c d e f g h i j k l m n o p q r s t u v w x y z { } ~

The following characters can be used with the stated limitations:

  • ` needs backslash before this character

  • – cannot be the first character

  • . cannot be the last character

  • = cannot be the filename without other characters

The following characters cannot be used in filenames:

" ( ) * , / : < > ? \ |

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 location all keywords.

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

When no alias 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. Network Protocols Supported by 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

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.

sftp:

Secure File Transfer Protocol

SFTP is an application protocol is used for secure transferring files between the router and and an archieve server. SFTP requires a username and password.

scp:

Secure Copy Protocol

SCP is an application protocol is used for secure transferring files between the router and and an archieve server. SFTP requires a username and password.

Additional usage guidelines are in the following sections.

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 | all}]

Example:

RP/0/RP0/CPU0:router# copy tftp://1.1.1.1/images/software.pie disk1:

Note


Some Cisco IOS XR 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. 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 | all}]

    Example:
    
    RP/0/RP0/CPU0:router# copy ftp://john:secret@10.1.1.1/images/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 hostname, 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 hostname.

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.

Using xml-schema

Use the xml-schema keyword to obtain the most up-to-date XML schemas (.xsd files) from the router. Using this keyword is useful to prevent the use of outdated schemas in the event that router software updates include schema updates. The tar ball file includes all active schema files. It does not include schemas that are activated by specific package installation envelopes (PIEs) if those PIEs are not installed and activated on the router.

Copying to the Running Configuration

When you use the copy command to copy a configuration file to the running-config destination, the configuration in the file is applied to the running configuration of the system. This is a configuration operation. By default, the copy is carried out in a best-effort manner. This means that if some configuration lines from the file cannot be applied, the remaining configuration is still integrated into the system. In this case, a partial configuration is committed. When the atomic keyword is used, partial configurations are not committed. This means that even if one error occurs in the parsing or committing phase, no changes are made to the system. To view any errors when applying the configuration, use the show configuration failed command.
