When ES4624-SFP/ES4626-SFP switch operates as a FTP/TFTP client, configuration
files or system files can be downloaded from the remote FTP/TFTP servers(can be hosts
or other switches) without affecting its normal operation. And file list can also be retrieved
from the server in ftp client mode. Of course, ES4624-SFP/ES4626-SFP switch can also
upload current configuration files or system files to the remote FTP/TFTP servers(can be
hosts or other switches). When ES4624-SFP/ES4626-SFP switch operates as a
FTP/TFTP server, it can provide file upload and download service for authorized
FTP/TFTP clients, as file list service as FTP server.
Here are some terms frequently used in FTP/TFTP.
ROM: Short for EPROM, erasable read-only memory. EPROM is repalced by FLASH
memory in ES4624-SFP/ES4626-SFP 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 ES4624-SFP/ES4626-SFP
switch, the system image file is allowed to save in FLASH only.
ES4624-SFP/ES4626-SFP 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 ES4624-SFP/ES4626-SFP switch,
the boot file is allowed to save in ROM only. ES4624-SFP/ES4626-SFP 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.
ES4624-SFP/ES4626-SFP switch start up configuration file stores in FLASH only,
corresponding to the so called configuration save. To prevent illicit file upload and easier
configuration, ES4624-SFP/ES4626-SFP 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 ES4624-SFP/ES4626-SFP 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
