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; for more information, refer to Configuring
the Enable Password.
CONFIGURATION mode — allows you to configure security features, time settings, set logging and
simple network management protocol (SNMP) functions, and static address resolution protocol (ARP)
and MAC addresses on the system.
Beneath CONFIGURATION mode are sub-modes that apply to interfaces, protocols, and features. The
following example shows this sub-mode command structure. When configuring the chassis for the first
time, two sub-CONFIGURATION modes are important:
INTERFACE sub-mode — 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, 10-Gigabit
Ethernet, 40-Gigabit Ethernet, or 2/4/8-Gigabit Universal Port) or logical (Loopback, Null, port
channel, or virtual local area network [VLAN]).
LINE sub-mode — 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 the
available commands, including the possible sub-modes.
