NNCLI command modes
This section describes the use and purpose of NNCLI command modes.
NNCLI command modes separate basic user tasks from control and
management of the switch.
These command modes are available in NNCLI:
•
User Executive
• Privileged Executive
•
Global Configuration
•
Interface Configuration
Command mode access is determined by access permission levels and
password protection.
If no password is set, you can open NNCLI in User Executive mode
and perform the
enable command to move to the next level, Privileged
Executive mode.
However, if you have read-only access, you cannot progress beyond User
Executive mode, the default mode.
If you have read-write access you can progress from the default mode
through all of the available modes.
User Executive mode is the default NNCLI command mode and the initial
access mode. Also known as exec mode, it is the most restrictive NNCLI
mode with only basic commands available; for example, show, ping and
logout. User Executive commands are available from the other modes.
Privileged Executive mode is an unrestricted mode that can display all
switch settings. If you are logged on with write access, you can access
all configuration modes and commands that affect switch operation from
Privileged Executive mode.
In Privileged Executive mode, also known as privExec mode, you can
perform basic switch level management tasks; for example, downloading
software images, setting passwords, and starting the switch. Privileged
Executive commands are also available in Global and Interface
configuration modes.
Global Configuration mode, also known as config mode, provides
commands used to set and display general switch configurations such as
IP address, Simple Network Management Protocol (SNMP) parameters,
Telnet access, and Virtual Local Area Networks (VLAN).
