CLI Modes
Different sets of commands are available in each mode.
A command found in one mode cannot be executed from another mode (except for EXEC mode commands
with a preceding
do
command (refer to the
do
Command section).
You can set user access rights to commands and command modes using privilege levels.
For more information about privilege levels and security options, refer to the Privilege Levels Overview section
in the Security chapter.
The Dell Networking OS CLI is divided into three major mode levels:
• EXEC mode is the default mode and has a privilege level of 1, which is the most restricted level. Only a
limited selection of commands is available, notably the
show
commands, which allow you to view
system information.
• EXEC Privilege mode has commands to view configurations, clear counters, manage configuration files,
run diagnostics, and enable or disable debug operations. The privilege level is 15, which is unrestricted.
You can configure a password for this mode; refer to the Configure the Enable Password section in the
Getting Started chapter.
• CONFIGURATION mode allows you to configure security features, time settings, set logging and SNMP
functions, configure static ARP and MAC addresses, and set line cards on the system.
Beneath CONFIGURATION mode are submodes that apply to interfaces, protocols, and features. The
following example shows the submode command structure. Two sub-CONFIGURATION modes are
important when configuring the chassis for the first time:
• INTERFACE submode is the mode in which you configure Layer 2 and Layer 3 protocols and IP services
specific to an interface. An interface can be physical (Management interface, 1 Gigabit Ethernet, 10
Gigabit Ethernet, 25 Gigabit Ethernet, 40 Gigabit Ethernet, 50 Gigabit Ethernet, or 100 Gigabit Ethernet)
or logical (Loopback, Null, port channel, or virtual local area network [VLAN]).
• LINE submode is the mode in which you to configure the console and virtual terminal lines.
NOTE: At any time, entering a question mark (
?
) displays the available command options. For example,
when you are in CONFIGURATION mode, entering the question mark first lists all available commands,
including the possible submodes.
