Chapter 4 Basic Switch Configuration
4-18
Here are some terms frequently used in FTP/TFTP.

ROM: Short for EPROM, erasable read-only memory. EPROM is repalced by FLASH memory in
switch.

SDRAM: RAM memory in the switch, used for system software operation and configuration
sequence storage.

FLASH: Flash memory used to save system file and configuration file.

System file: including system image file and boot file.

System image file: refers to the compressed file for switch hardware driver and software support
program, usually refer to as IMAGE upgrade file. In switch, the system image file is allowed to save
in FLASH only. Switch mandates the name of system image file to be uploaded via FTP in Global
Mode to be nos.img, other IMAGE system files will be rejected.

Boot file: refers to the file initializes the switch, also referred to as the ROM upgrade file (Large
size file can be compressed as IMAGE file). In switch, the boot file is allowed to save in ROM only.
Switch mandates the name of the boot file to be boot.rom.

Configuration file: including start up configuration file and running configuration file. The
distinction between start up configuration file and running configuration file can facilitate the
backup and update of the configurations.

Start up configuration file: refers to the configuration sequence used in switch start up. Switch
start up configuration file stores in FLASH only, corresponding to the so called configuration save.
To prevent illicit file upload and easier configuration, switch mandates the name of start up
configuration file to be startup-config.

Running configuration file: refers to the running configuration sequence use in the switch. In
switch, the running configuration file stores in the RAM. In the current version, the running
configuration sequence running-config can be saved from the RAM to FLASH by write command
or copy running-config startup-config command, so that the running configuration sequence
becomes the start up configuration file, which is called configuration save. To prevent illicit file
upload and easier configuration, switch mandates the name of running configuration file to be
running-config.

Factory configuration file: The configuration file shipped with switch in the name of factory-config.
Run set default and write, and restart the switch, factory configuration file will be loaded to
overwrite current start up configuration file.
4.5.3.2 FTP/TFTP Configuration
The configurations of switch as FTP and TFTP clients are almost the same, so the configuration procedures
for FTP and TFTP are described together in this manual.
