Using The Undo Form Of A Command; Cli Views - HP 830 Series Configuration Manual

The following example analyzes the syntax of the clock datetime time date command by using the
conventions in
Figure 2 Understanding command-line parameters
For example, to set the system time to 10:30:20, February 23, 2012, enter the following command line
at the CLI and press Enter:
<Sysname> clock datetime 10:30:20 2/23/2012

Using the undo form of a command

Most configuration commands have an undo form for canceling a configuration, restoring the default, or
disabling a feature. For example, the info-center enable command enables the information center, and
the undo info-center enable command disables the information center.

CLI views

Commands are grouped in different views by function. To use a command, you must enter its view.
CLI views are hierarchically organized, as shown in
you can identify where you are and what you can do. For example, the prompt
shows that you are in VLAN 100 view and can configure attributes for that VLAN.
You are placed in user view immediately after you are logged in to the CLI. The user view prompt is
<Device-name>, where the Device-name argument, representing the device hostname, defaults to HP
and can be changed by using the sysname command. In user view, you can perform basic operations,
including display, debug, file management, FTP, Telnet, clock setting, and reboot.
From user view, you can enter system view to configure global settings, including the daylight saving time,
banners, and hotkeys. The system view prompt is [Device-name].
From system view, you can enter different function views. For example, you can enter interface view to
configure interface parameters, enter VLAN view to add ports to the specific VLAN, and enter user
interface view to configure login user attributes.
To display all commands available in a view, enter a question mark (?) at the view prompt.
