Follow these steps to configure connection idle time: 

Enter system view 

— 

Configure the connection idle time 
for the FTP server 

ftp timeout minutes 

Optional 

30 minutes by default 

 

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. 

 

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. 

 

Follow these steps to specify the source interface and source IP address for an FTP server: 

Enter system view 

— 

Specify the source interface for 
an FTP server 

ftp-server source-interface 
interface-type interface-number 

Specifying the source IP 
address for an FTP server 

ftp-server source-ip ip-address 

Use either command 

Not specified by default. 

 

z 

The specified interface must be an existing one. Otherwise a prompt appears to show that the 

configuration fails. 

z 

The value of the ip-address argument must be an IP address on the device where the configuration 

is performed. Otherwise a prompt appears to show that the configuration fails. 

z 

You can specify only one source interface or source IP address for the FTP at one time. That is, 

only one of the commands ftp-server source-interface and ftp-server source-ip can be valid at 

one time. If you execute both of them, the new setting will overwrite the original one. 

z 

If the switch (FTP server) is the command switch or member switch in a cluster, do not use the 

ftp-server source-ip command to specify the private IP address of the cluster as the source IP 

address of the FTP server. Otherwise, FTP does not take effect.
