118 Appendix C: Using FTP

What is FTP?

FTP is a session-oriented tool, which means that you establish a session,
through login, before the file exchange takes place. The login requires a secure
userID and password. Create the secure userID and password via the FTP level
or the FTP MIB using SNMP.
FTP on the DMS-100 switch conforms to industry standards regulating FTP.
As a result, users can exchange files between the computing module (CM), file
processors (FP), UNIX workstations or PCs, mainframes, and other computing
platforms that have an industry-standard implementation of FTP.
In an established session, each FTP implementation on the connected
platforms works either as the server or the client, such that you can transfer
files to or from a host.
FTP on the DMS-100 switch provides the following functionalities:

Automatic Record Length Detection

The FTP application automatically detects and sets the record length for files
with acceptable file extensions. The system defaults to the automatic record
length detection option.
When the automatic record length detection option is active, the system
recognizes the following two file formats:
•
•
Before the transfer, the FTP application attempts to determine the file type and
record length by parsing the extension of the file. The FTP application
identifies files with extensions made up of a shortened form of the transfer type
and record length. These files are in the following format:
<filename>.<bin/txt><record length>

297-8991-910 Standard 03.01 August 1999
automatically detects the file type and logical record length based on the
filename extension
lists available active disk volumes
automatically capitalizes filenames
filename extensions made up of a shortened form of the transfer type and
record length such as the extension .bin256
filename extensions that are the same as a defined set of common
extensions
Note: Before the transfer takes place, issue the BINARY or ASCII
command.
