Exec Command Mode; Global Configuration Command Mode; Interface Configuration Command Mode - Cisco Nexus 5500 Series Configuration Manual

Understanding the Command-Line Interface

EXEC Command Mode

When you first log in, the Cisco NX-OS software places you in EXEC mode. The commands available in
EXEC mode include the show commands that display the device status and configuration information, the
clear commands, and other commands that perform actions that you do not save in the device configuration.

Global Configuration Command Mode

Global configuration mode provides access to the broadest range of commands. The term indicates
characteristics or features that affect the device as a whole. You can enter commands in global configuration
mode to configure your device globally or to enter more specific configuration modes to configure specific
elements such as interfaces or protocols.

Interface Configuration Command Mode

One example of a specific configuration mode that you enter from global configuration mode is interface
configuration mode. To configure interfaces on your device, you must specify the interface and enter interface
configuration mode.
You must enable many features on a per-interface basis. Interface configuration commands modify the operation
of the interfaces on the device, such as Ethernet interfaces or management interfaces (mgmt 0).
For more information about configuring interfaces, see the Cisco Nexus interfaces guide for your device.
