The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Secure Shell (SSH) includes support for SSH File Transfer Protocol (SFTP), which is a new standard file transfer protocol introduced in SSHv2. This feature provides a secure and authenticated method for copying device configuration or device image files.
SSH must be enabled.
The ip ssh source-interface interface-type interface-number command must be configured.
The SFTP server is not supported.
SFTP boot is not supported.
The sftp option in the install add command is not supported.
The SFTP client functionality is provided as part of the SSH component and is always enabled on the corresponding device. Therefore, any SFTP server user with the appropriate permission can copy files to and from the device.
An SFTP client is VRF-aware; you can configure the secure FTP client to use the virtual routing and forwarding (VRF) associated with a particular source interface during connection attempts.
The following sections provide information about the various tasks that comprise an SFTP configuration.
Perform the following steps:
To configure a Cisco device for SFTP client-side functionality, the ip ssh source-interface interface-type interface-number command must be configured first.
| Command or Action | Purpose | |
|---|---|---|
|
Step 1 |
enable Example: |
Enables privileged EXEC mode.
|
|
Step 2 |
configure terminal Example: |
Enters global configuration mode. |
|
Step 3 |
ip ssh source-interface interface-type interface-number Example: |
Defines the source IP for the SSH session. |
|
Step 4 |
exit Example: |
Exits global configuration mode and returns to privileged EXEC mode. |
|
Step 5 |
show running-config Example: |
(Optional) Displays the SFTP client-side functionality. |
|
Step 6 |
debug ip sftp Example: |
(Optional) Enables SFTP debugging. |
SFTP copy takes the IP or hostname of the corresponding server if Domain Name System (DNS) is configured. To perform SFTP copy operations, use the following commands in privileged EXEC mode:
|
Command |
Purpose |
|---|---|
|
Device# copy ios-file-system:file sftp://user:pwd@server-ip//filepath Or Device# copy ios-file-system: sftp: |
Copies a file from the local Cisco IOS file system to the server. Specify the username, password, IP address, and filepath of the server. |
|
Device# copy sftp://user:pwd@server-ip //filepath ios-file-system:file Or Device# copy sftp: ios-file-system: |
Copies the file from the server to the local Cisco IOS file system. Specify the username, password, IP address, and filepath of the server. |
The following example shows how to configure the client-side functionality of SFTP:
Device> enable
Device# configure terminal
Device(config)# ip ssh source-interface gigabitethernet 1/0/1
Device(config)# exit
