Basic Command Information
48 Chapter 2 Command Descriptions
Verifying Device Support for Commands
For verification that a device supports a particular command, you can enter
several commands. For example:
• “help” displays all supported commands for a device.
• “?” displays all supported commands for a device.
• “set ?” displays the syntax and options for the “set” command. You can
use this to determine whether the device includes a particular “set”
command variant.
• “help set” displays syntax and options for the “set” command.
• “set service ?” displays the syntax and options for the “set service”
command.
• “help set service” displays the syntax and options for the “set service”
command.
Some options may become available in new firmware revisions or before
new documentation is released.
Some commands relate only to particular features unique to specific
devices. Other commands may have options that are specific to features
that are not available on all devices. These device-specific commands and
options are noted in the command descriptions.
Abbreviating Commands
All commands can be abbreviated by suppling enough letters to uniquely
identify the command.
Syntax Conventions
Presentation of command syntax in this manual follows these conventions:
• Brackets [ ] surround optional material.
• Braces { } surround entries that require you to chose one of several
options, which are separated by the vertical bar |.
• Non-italicized text indicates literal values, that is, options or values that
must be typed exactly as they appear. "yes" and "no" option values are
are examples of literals.
• Italicized text indicates that a type of information is required in that
option. For example, filename means that the name of a file is required
in the option.
