Transferring Files Using HTTP or HTTPS

First Published: May 5, 2005
Last Updated: May 14, 2009

Cisco IOS Release 12.4 provides the ability to transfer files between your Cisco IOS software-based device and a remote HTTP server using the HTTP or HTTP Secure (HTTPS) protocol. HTTP and HTTPS can now be specified as the targets and source locations in Cisco IOS command-line interface (CLI) commands that use file system prefixes such as the copy command.

Prerequisites for Transferring Files Using HTTP or HTTPs

To copy files to or from a remote HTTP server, your system must support the HTTP client feature, which is integrated in most Cisco IOS software images. The HTTP client is enabled by default. To determine if the HTTP client is supported on your system, issue the show ip http client all command. If you are able to execute the command, the HTTP client is supported.

Commands exist for the optional configuration of the embedded HTTP client and for the HTTPS client, but the default configuration is sufficient for using the File Transfer Using HTTP or HTTPS feature. For information on configuring optional HTTP or HTTPS client characteristics, see the "Related Documents" section.

Restrictions for Transferring Files Using HTTP or HTTPs

Existing limitations to the copy command, such as no network-to-network copies, are in effect for the File Transfer Using HTTP or HTTPS feature.

Note The copy command in Cisco IOS Release 12.4T does not work in conjunction with older versions of the Apache server software. The Apache server software must be upgraded to version 2.0.49 or later in order to use the copy command.

Information About File Transfers Using HTTP or HTTPs

To transfer files using HTTP or HTTPS, you should understand the following concept:

The File Transfer Using HTTP or HTTPs feature provides the capability to copy files, such as Cisco IOS image files, core files, configuration files, log files, scripts, and so on, to and from a remote server and your local routing device using the Cisco IOS copy command and command-line interface. The HTTP copy operation works in the same way as copying from other remote file systems, such as FTP or TFTP.

The HTTP copy operation can use the embedded HTTPS client for HTTP Secure transfers, providing secure and authenticated file transfers within the context of a public key infrastructure (PKI).

How to Transfer Files Using HTTP or HTTPs

This section contains the following procedures:

•Configuring HTTP Connection Characteristics for File Transfers (as required)

•Downloading a File from a Remote Server Using HTTP or HTTPs (required)

•Uploading a File to a Remote Server Using HTTP or HTTPS (required)

•Maintaining and Monitoring File Transfers Using HTTP (optional)

Note To use the File Transfer Using HTTP feature, you may need to specify a username and password for the HTTP connections for those servers that require a username and password to connect. Commands are also available to specify custom connection characteristics, although default settings can be used. The feature also offers commands to monitor and maintain connections and files.

Configuring HTTP Connection Characteristics for File Transfers

Default values are provided for HTTP File transfers. The following task is used to customize the connection characteristics for your network to specify a username and password, connection preferences, a remote proxy server, and the source interface to be used.

SUMMARY STEPS

1. enable

2. configure terminal

3. ip http client connection {forceclose | idle timeout seconds | timeout seconds}

4. ip http client username username

5. ip http client password password

6. ip http client proxy-server {proxy-name | ip-address} [proxy-port port-number]

7. ip http client source-interface interface-id

8. do copy running-config startup-config

9. end

DETAILED STEPS

 
Command or Action
Purpose

Step 1 

enable

Example:

Router> enable

Enables privileged EXEC mode.

•Enter your password if prompted.

Step 2 

configure terminal

Example:

Router# configure terminal

Enters global configuration mode.

Step 3 

ip http client connection {forceclose | idle timeout seconds | timeout seconds}

Example:

Router(config)# ip http client connection timeout 15

Configures characteristics for HTTP client connections to a remote HTTP server for all file transfers:

•forceclose—Disables the default persistent connection.

•idle timeout seconds—Sets the period of time allowed for an idle connection, in a range from 1 to 60 seconds. Default timeout is 30 seconds.

•timeout seconds—Sets the maximum time the HTTP client waits for a connection, in a range from 1 to 60 seconds. Default is 10 seconds.

Step 4 

ip http client username username

Example:

Router(config)# ip http client username user1

Specifies the username to be used for HTTP client connections that require user authentication.

Note You can also specify the username on the CLI when you issue the copy command, in which case the username entered overrides the username entered with this command. See the "Downloading a File from a Remote Server Using HTTP or HTTPs: Example" section for an example.

Step 5 

ip http client password password

Example:

Router(config)# ip http client password letmein

Specifies the password to be used for HTTP client connections that require user authentication.

Note You can also specify the password on the CLI when you issue the copy command, in which case the password entered overrides the password entered with this command. See the "Downloading a File from a Remote Server Using HTTP or HTTPs: Example" section for an example.

Step 6 

ip http client proxy-server {proxy-name | ip-address} [proxy-port port-number]

Example:

Router(config)# ip http client proxy-server edge2 proxy-port 29

Configures the HTTP client to connect to a remote proxy server for HTTP file system client connections.

•The optional proxy-port port-number keyword and argument specify the proxy port number on the remote proxy server.

Step 7 

ip http client source-interface interface-id

Example:

Router(config)# ip http client source-interface Ethernet 0/1

Specifies the interface for the source address in all HTTP client connections.

Step 8 

do copy running-config startup-config

Example:

Router(config)# do copy running-config startup-config

(Optional) Saves the running configuration as the startup configuration file.

•The do command allows you to execute privileged EXEC mode commands from global configuration mode.

Step 9 

end

Example:

Router(config)# end

Router#

Ends your configuration session and returns the CLI to user EXEC mode.

Downloading a File from a Remote Server Using HTTP or HTTPs

Perform this task to download a file from a remote HTTP server using HTTP or HTTPs. The copy command helps you to copy any file from a source to a destination.

SUMMARY STEPS

1. enable

2. copy [/erase] [/noverify] http://remote-source-url  local-destination-url

or

copy https://remote-source-url  local-destination-url

DETAILED STEPS

 
Command or Action
Purpose

Step 1 

enable

Example:

Router> enable

Enables privileged EXEC mode.

•Enter your password if prompted.

Step 2 

copy [/erase] [/noverify] http://remote-source-url local-destination-url

or

copy https://remote-source-url local-destination-url

Example:

Router# copy http://user1:mypassword@209.165.202.129:808 0/image_files/c7200-i-mx flash:c7200-i-mx

Example:

Router# copy

copy https://user1:mypassword@209.165.202.129:80 80/image_files/c7200-i-mx flash:c7200-i-mx

Copies a file from a remote web server to a local file system using HTTP or HTTPS.

•/erase—Erases the local destination file system before copying. This option is provided on Class B file system platforms with limited memory to allow an easy way to clear local flash memory space.

•/noverify—If the file being copied is an image file, this keyword disables the automatic image verification that occurs after an image is copied.

•The remote-source-url argument is the location URL (or alias) from which to get the file to be copied, in standard Cisco IOS file system HTTP syntax as follows:

http://[[username:password]@] {hostname | host-ip}[/filepath]/filename

Note The optional username and password arguments can be used to log in to an HTTP server that requires user authentication, in place of configuring the ip http client username and ip http client password global configuration commands to specify these authentication strings.

•The local-destination-url is the location URL (or alias) to put the copied file, in standard Cisco IOS file system syntax as follows:

filesystem:[/filepath][/filename]

Note For more information on URL syntax when you use the copy command, see the "Additional References" section.

Troubleshooting Tips

If file transfers from a remote web server fail, verify the following:

•Your router has an active connection to the Internet.

•The correct path and filename have been specified.

•The remote server requires a username and password.

•The remote server has a nonstandard communications port configured. (The default port for HTTP is 80; the default port for HTTPS is 443.)

The CLI returns error messages to help you determine the cause of a failed copy request. Additional information on the copy process can be displayed with the debug ip http client all command.
