Glossary 585
CDMA (code division multiple access)
A mobile data service available to users of CDMA mobile phones.
CHAP (challenge handshake authentication protocol)
An authentication protocol used for PPP authentication. See MS-CHAP.
checksum
Software posted at the Cyclades download site is accompanied by a checksum
(*.md5) file generated using the MD5 algorithm. The checksum of a
downloaded file must be the same as the checksum in the file. The checksum
is compared automatically when the download is performed through the Web
Manager or can be compared manually if the download is performed using
ftp or http. If the checksums do not match, the software file is damaged
and should not be used.
CLI (command line interface)
Allows users to use text commands to tell computers to perform actions (in
contrast to using a GUI). The user types a text command at an on-screen
prompt and presses the Enter or Return key. The computer processes the
command, displays output when appropriate, and displays another prompt.
Users can save a series of frequently-used commands in a script. Being able to
create and run scripts to automate repetitive tasks is one of the reasons many
administrators prefer using a CLI.
Cyclades products run the Linux operating system, and most Cyclades
products allow access to the command line of the Linux shell. Command line
access is achieved through several different means. For one example, a remote
administrator can use Telnet or SSH to access an AlterPath OnBoard and then
can enter commands on the Linux shell's command line.
Some Cyclades products offer a management utility called the CLI.
Administrators type “CLI” or “cli” at the prompt in the Linux shell. Products
that provide similar utilities with different names, such as the cycli, provide
an alias for users who are familiar with the CLI name. The Cyclades CLI tool
provides many commands and nested parameters in a format called the CLI
parameter tree.
