3 User Interfaces
3.1

Command Line Interface (CLI)

MLNX-OS® is equipped with an industry-standard CLI. The CLI is accessed through SSH or
Telnet sessions, or directly via the console port on the front panel (if it exists).
Refer to the MLNX-OS Command Reference Guide for complete set of commands, syntax and
examples.
3.1.1

CLI Modes

The CLI can be in one of following modes, and each mode makes available a certain group (or
level) of commands for execution. The different CLI configuration modes are:

Config Interface Port Channel
Config Vlan
Any Command Mode
When the CLI is launched, it begins in Standard mode. This is the
most restrictive mode and only has commands to query a
restricted set of state information. Users cannot take any actions
that directly affect the system, nor can they change any configu-
ration.
The enable command moves the user to Enable mode. This
mode offers commands to view all state information and take
actions like rebooting the system, but it does not allow any con-
figurations to be changed. Its commands are a superset of those
in Standard mode.
The configure terminal command moves the user from
Enable mode to Config mode. Config mode is allowed only for
user accounts in the "admin" role (or capabilities). This mode has
a full unrestricted set of commands to view anything, take any
action, and change any configuration. Its commands are a super-
set of those in Enable mode. To return to Enable mode, enter
exit or no configure.
Note that moving directly from/to Standard mode to/from Config
mode is not possible.
Configuration mode for management interface mgmt0, mgmt1
and loopback.
Configuration mode for Ethernet interface.
Configuration mode for Port channel (LAG).
Configuration mode for VLAN.
Several commands such as "show" can be applied within any
context.
