The [No] Prefix - Cisco SCE8000 Configuration Manual

Chapter 2 Command Line Interface
When asking for help on particular parameter, the system informs you of the type of data that is an
accepted legal value. The types of parameters supported are:
STRING
DECIMAL Any decimal number. Positive number is assumed, for negative numbers use the "–"
HEX
Example:
The following example illustrates the use of ? to get help on commands syntax. In this example, you can
enter either the word running-config, or any name of a file, after the word copy.
SCE#copy?
running-config Copy running configuration file
startup-config Backup the startup-config to a specified destination
STRING Source file
SCE#copy

The [no] Prefix

Many CLI commands offer the option of adding the word no before the command to disable the feature
controlled by the command or revert it to its default configuration. This notation is often shown as [no]
to denote it is optional.
For example, the command service telnetd enables the telnet server, while the no service telnetd
command disables the telnet server.
