z 

Only one user can access a 3com switch 5500-EI at a given time when the latter operates as an 

FTP server.  

z 

Operating as an FTP server, a 3com switch 5500-EI 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 5500-EI 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 5500-EI 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. 

 

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.
