z
Only one user can access a 3com switch 4500 at a given time when the latter operates as an FTP
server.
z
Operating as an FTP server, a 3com switch 4500 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.
z
When you log in to a Fabric consisting of multiple switches through an FTP client, after the FTP
client passes authentication, you can log in to the master device of the Fabric.
z
You cannot access a 3com switch 4500 operating as an FTP server through Microsoft Internet
Explorer. To do so, use other client software.
To protect unused sockets against attacks, the 3com switch 4500 provides the following functions:
z
TCP 21 is enabled only when you start the FTP server.
z
TCP 21 is disabled when you shut down the FTP server.

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.
