Operation Manual – FTP-SFTP-TFTPH3C S5600 Series Ethernet Switches Chapter 1 FTP and SFTP Configuration1-19Note:z Currently an H3C S5600 series Ethernet switch operating as an SFTP serversupports the connection of only one SFTP user. When multiple users attempt to login to the SFTP server or multiple connections are enabled on a client, only the firstuser can log in to the SFTP user. The subsequent connection will fail.z When you upload a large file through WINSCP, if a file with the same name existson the server, you are recommended to set the packet timeout time to over 600seconds, thus to prevent the client from failing to respond to device packets due totimeout. Similarly, when you delete a large file from the server, you arerecommended to set the client packet timeout time to over 600 seconds.1.3.2 SFTP Configuration: A Switch Operating as an SFTP ClientI.
