Note:
Only one user can access an H3C S3100 series Ethernet switch at a given time
when the latter operates as an FTP server.
Operating as an FTP server, an H3C S3100 series Ethernet switch cannot receive a
file whose size exceeds its storage space. The clients that attempt to upload such a
file will be disconnected with the FTP server due to lack of storage space on the FTP
server.
You cannot access an H3C S3100 series switch operating as an FTP server
through Microsoft Internet Explorer. To do so, use other client software.
Note:
To protect unused sockets against attacks, the S3100 Ethernet switch provides the
following functions:
TCP 21 is enabled only when you start the FTP server.
TCP 21 is disabled when you shut down the FTP server.
III. 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.
