Juniper JUNOSE 11.3, Configuration Manual

Page: 109 / 632

NOTE: Within any configuration mode, the commands that are available to
the user include the commands defined for that configuration mode and all
commands defined for Global Configuration mode. See Figure 21 on page 28.
For example, from Router Configuration mode, you could use the
interface
Global Configuration mode command without first explicitly going back to
Global Configuration mode.
host1(router-config)# interface atm 4/0.3
host1(config-if)#
Exec Modes
There are two Exec modes: User Exec and Privileged Exec.
After you log in to the system, the CLI is in User Exec mode. By default, the commands
you can execute from User Exec mode provide only user-level access; however, you
should password protect it to prevent unauthorized use. The User Exec commands allow
you to perform such functions as:
•
Change terminal settings on a temporary basis.
• Perform ping and trace commands.
• Display system information.
