Navigating The CLI
HUAWEI TECHNOLOGIES CO., LTD.
Foreword
The implementation of Huawei devices in an enterprise network requires
a level of knowledge and capability in the navigation of the VRP
command line interface, and configuration of system settings. The
principle command line architecture is therefore introduced as part of this
section along with navigation, help functions and common system
settings that are required to be understood for the successful
configuration of any VRP managed device.
