Chapter 1 FTP and TFTP Configuration
1-4
Note:
z
Only one user can access an S3100-52P Ethernet 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.
z
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.
z
Operating as an FTP server, an S3100-52P 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.
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.
