54 CHAPTER 3: SYSTEM MANAGEMENT
The names of the program/configuration file are “system” and “config”
respectively by default. In the command, file-name is a character string with the
length of 1 to 30.
2 Set FTP update mode
When logging onto the FTP Server from a PC, you can use the put command to
upload the file. The FTP Server adopts two update modes: fast update mode and
normal update mode.
■ Fast update mode: In this mode, after the FTP Server has received the files
uploaded by the user, it will write the files into Flash. Even when the power is
disconnected during the period of transmitting the files, the existing files in the
router will not be destroyed.
■ Normal update mode: In this mode, the FTP Server writes the files uploaded by
the user into Flash as it receives the files. The existing files in the router may be
destroyed due to power disconnection. Compared with fast update mode, the
system demands less empty memory in the router when working in normal
update mode.
Please perform the following configuration in system view.
Table 33 Set FTP update mode
By default, the FTP server adopts fast update mode.
3 Set the connection time limit of FTP service.
To prevent illegal access by unauthorized users, if no service request from the FTP
