Operation Manual – FTP-SFTP-TFTPH3C S3100 Series Ethernet Switches Chapter 1 FTP and SFTP Configuration1-15Note:z Currently an H3C S3100 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. Basic configurations on an SFTP clientBy default a switch can operate as an SFTP client. In this case you can connect theswitch to the SFTP server to perform SFTP-related operations (such ascreating/removing a directory) by executing commands on the switch. Table 1-13 liststhe operations that can be performed on an SFTP client.Table 1-13 Basic configurations on an SFTP clientOperation Command DescriptionEnter system view system-view —Enter SFTP client viewsftp { host-ip |host-name } [ port-num ][ identity-key { dsa | rsa }| prefer_kex { dh_group1| dh_exchange_group } |prefer_ctos_cipher { des| aes128 } |prefer_stoc_cipher { des| aes128 } |prefer_ctos_hmac{ sha1 | sha1_96 | md5 |md5_96 } |prefer_stoc_hmac{ sha1 | sha1_96 | md5 |md5_96 } ] *Required
