These hotkeys are defined by the device. When you interact with the device from
terminal software, these keys may be defined to perform other operations. If so,
the definition of the terminal software will dominate.
Configuring User Levels
and Command Levels
All the commands are defaulted to different views and categorized into four levels:
visit, monitor, system, and manage, identified respectively by 0 through 3. If you
want to acquire a higher privilege, you must switch to a higher user level, and it
requires password to do so for the security’s sake.
The following table describes the default level of the commands.
Follow these steps to configure user level and command level:
n
The commands available depend on your user level when you log onto a device.
For example, if your user level is 3 and the command level of VTY 0 interface is 1,
you can use commands below level 3 (inclusive).

CAUTION:
■
When you configure the password for switching user level with the super
password command, the user level is defaulted to 3 if no user level is
specified.
■
You can switch to a lower user level unconditionally. To switch to a higher user
level, however, you need to enter the password needed (The password can be
set with the
super password command.). If the entered password is incorrect
or no password is configured, the switch fails. Therefore, before switching to a
higher user level, you should configure the password needed.
<Esc+<> Specifies the cursor as the beginning of the clipboard.
<Esc+>> Specifies the cursor as the ending of the clipboard.
