sftp client-source

sftp client-source

Function

The sftp client-source command specifies the source IP address for the SFTP client to send packets.

The undo sftp client-source command restores the default source IP address for the SFTP client to send packets.

The default source IP address for the SFTP client to send packets is 0.0.0.0.

Format

sftp client-source { -a source-ip-address | -i interface-type interface-number }

undo sftp client-source

Parameters

Parameter Description Value
-a source-ip-address

Specifies the source IP address. You are advised to use the loopback interface IP address.

 The value is in dotted decimal notation.
-i interface-type interface-number

Specifies the source interface. You are advised to use the loopback interface.

The IP address configured for the source interface is the source IP address for sending packets. If no IP address is configured for the source interface, the FTP connection cannot be set up.

Usage Guidelines

Usage Scenario

If no source IP address is specified, the client uses the source IP address that the router specifies to send packets. The source IP address must be configured for an interface with stable performance. The loopback interface is recommended. Using the loopback interface as the source interface simplifies the ACL rule and security policy configuration. This shields the IP address differences and interface status impact, and incoming and filters outgoing packets, and implements security authentication.

Precautions

  • You can query the source IP address or primary IP address of the source interface for the SFTP connection on the SFTP server.

  • The sftp command also configures the source IP address whose priority is higher than that of the source IP address specified in the sftp client-source command. If you specify source addresses in the sftp client-source and sftp commands, the source IP address specified in the sftp command is used for data communication. The source address specified in the sftp client-source command applies to all SFTP connections. The source address specified in the sftp command applies only to the current SFTP connection.

Example

# Set the source IP address of the SFTP client to 1.1.1.1.

<Huawei> system-view
[Huawei] sftp client-source -a 1.1.1.1
Info: Succeeded in setting the source address of the SFTP client to 1.1.1.1
