SFTP Configuration 439
Configuring connection idle time
After the idle time is configured, if the server does not receive service requests
from a client within a specified time period, it terminates the connection with the
client, thus preventing a user from occupying the connection for a long time
without performing any operation.
Supported SFTP client software
A Switch 4210 operating as an SFTP server can interoperate with SFTP client
software, including SSH Tectia Client v4.2.0 (SFTP), v5.0, and WINSCP.
SFTP client software supports the following operations: logging in to a device;
uploading a file; downloading a file; creating a directory; modify a file name or a
directory name; browsing directory structure; and manually terminating a
connection.
For configurations on client software, see the corresponding configuration
manual.

■
Currently a Switch 4210 operating as an SFTP server supports the connection of
only one SFTP user. When multiple users attempt to log in to the SFTP server or
multiple connections are enabled on a client, only the first user can log in to
the SFTP user. The subsequent connection will fail.
■
When you upload a large file through WINSCP, if a file with the same name
exists on the server, you are recommended to set the packet timeout time to
over 600 seconds, thus to prevent the client from failing to respond to device
packets due to timeout. Similarly, when you delete a large file from the server,
you are recommended to set the client packet timeout time to over 600
seconds.

SFTP Client
Basic configurations on an SFTP client
By default a switch can operate as an SFTP client. In this case you can connect the
switch to the SFTP server to perform SFTP-related operations (such as
creating/removing a directory) by executing commands on the switch. Table 336
lists the operations that can be performed on an SFTP client.
