Operation Manual – FTP and TFTP
Quidway S5600 Series Ethernet Switches-Release 1510
Note:
Only one user can access an S5600 switch at a given time when the latter
operates as an FTP server.
FTP services are implemented in this way: An FTP client sends FTP requests to
the FTP server. The FTP server receives the requests, perform operations
accordingly, and return the results to the FTP client.
To prevent unauthorized accesses, an FTP server disconnects a FTP connection
when it does not receive requests from the FTP client for a specific period of time
known as the connection idle time.
An S5600 operating as an FTP server cannot receive a file whose size exceeds its
storage space. Those 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.
To use FTP services, a user must provide a user name and a password for being
authenticated by the FTP server.
III. Specifying the source interface and source IP address for an FTP server
You can specify the source interface and source IP address for an FTP server to
enhance server security. After this configuration, FTP clients can access this server
only through the IP address of the specified interface or the specified IP address.
Note:
Source interface refers to the existing VLAN interface or Loopback interface on the
device. Source IP address refers to the IP address configured for the interface on the
device. Each source interface corresponds to a source IP address. Therefore,
specifying a source interface for the FTP server is the same as specifying the IP
address of this interface as the source IP address.
