SFTP/SSH/SCP file transfer to/from 3560 switch

Jcotter001_2 · ‎07-30-2010

I am trying to transfer files to

3560 switch using one of the above protocols. I can connect to the switch via ssh

successfully for day to day mgmt. however when I run

WinSCP of filezilla I am

unable to establish a connection. I can authenticate successfuly but than receive the following error.

"Cannot initialize SFTP protocol. Is the host running a SFTP server"

As far as I can tell this should be possible or am I missing something? Thank you

debug and partial config below

Hi,

3560 switches do not support SFTP. WinSCP uses SFTP by default for connections. Hence the error.

3560 switches do support TFTP/FTP for the above, so use a TFTP/FTP server instead.
