If you specify to authenticate a client through public key on the server, the client needs to read the local 

private key when logging in to the SFTP server. Since both RSA and DSA are available for public key 

authentication, you need to use the identity-key key word to specify the algorithms to get correct local 

private key; otherwise you will fail to log in. For details, see SSH Operation.  

 

You can specify the source interface or source IP address for the device acting as an FTP client, so that 

it can connect to a remote SFTP server. 

Follow these steps to specify the source interface or source IP address for an SFTP client: 

Enter system view 

— 

Specify an interface as the 
source interface of the 
specified SFTP client 

sftp source-interface 
interface-type interface-number

Specify an IP address as the 
source IP address of the 
specified SFTP client 

sftp source-ip ip-address 

Use either command 

Not specified by default 

Display the source IP address 
used by the current SFTP client 

Optional 

Available in any view. 

 

As shown in 

, establish an SSH connection between the SFTP client (Switch A) and the SFTP 

server (switch B). Log in to Switch B through switch A to manage and transmit files. An SFTP user 

account with the user name client001 and password abc exists on the SFTP server.
