What device discovery modes are supported by Huawei eSight network management software?

The correct choice is based on the functionality provided by Huawei eSight network management software, particularly in the context of how devices can be discovered within a network. Batch import by Excel is a supported method, allowing users to import multiple devices simultaneously. This feature streamlines the process of adding devices to the network management system, making it efficient for network administrators who may be managing vast networks with many devices.

The ability to manage device discovery through Excel allows for easy updates and adjustments without the need for manual entry of each device individually. This reduces the time and potential errors associated with single-entry methods and is particularly beneficial for network environments where numerous devices need to be monitored and managed effectively.

While the other options might represent logical methods for device discovery, they may not align with the specific capabilities provided by Huawei eSight. For instance, device discovery by specified IP address or IP address segment might be standard in many network management tools, but the essence of this question is specifically about the methods supported by Huawei eSight, where batch operations via Excel play a significant role in enhancing efficiency and usability for network administrators.
