The default port number for logging in to the NetEco is
Answer(s): C
In Huawei NetEco access design, the Web client is reached using HTTPS to protect credentials and management data in transit. During initial deployment and commissioning, engineers access the NetEco login page by entering the server IP address followed by the default HTTPS service port. Huawei’s standard login method specifies that users open a browser and enter https://NetEco server IP:31943 to access the NetEco login interface. This port is therefore treated as the default Web login port in typical on-premises NetEco deployments, and it is the baseline value referenced in installation and login guidance. Other ports may appear in specific tools, customized scenarios, version variants, reverse-proxy deployments, or when security policy requires port changes, but those are exceptions driven by planning or product packaging. For exam and commissioning purposes, the correct default login port is the one used by the NetEco Web client entry point under the standard deployment model: 31943.
The NetEco supports manual backup and automatic backup.
Answer(s): A
NetEco is a management platform that stores critical operational data, including site configuration, device models, user/role information, historical alarms, trend data, reports, and northbound integration settings. To protect these assets and ensure service continuity, NetEco provides a built-in backup mechanism that supports both manual and automatic backup modes. Manual backup is typically used before major operations such as version upgrades, configuration changes, northbound interface adjustments, or large-scale device onboarding, so engineers can create a restore point on demand. Automatic backup is used for routine risk control and is normally implemented through scheduled tasks, allowing backups to be generated at defined intervals to reduce data-loss exposure in case of hardware failure, system corruption, or accidental misconfiguration. In standard O&M practice, automatic backups are combined with retention policies (for example, keeping a rolling set of backup files), storage capacity checks, and periodic restore verification to confirm backup integrity. This dual-mode backup capability is a foundational requirement for stable long-term operation of management systems like NetEco.
In alarm management, the status can be identified by masking rules.
Answer(s): A,C
In Huawei alarm management, masking rules are used to control how alarms are handled and displayed during specific conditions, such as planned maintenance, commissioning, device replacement, or known temporary abnormalities. When a masking rule is applied, the system can change how an alarm is classified so that O&M staff can distinguish between alarms that require immediate action and alarms that are expected or should be excluded from operational statistics. Two key statuses that masking rules can assign are Maintenance and Invalid. Maintenance indicates the alarm is generated during an approved maintenance activity (for example, power-off tests, sensor rewiring, cooling maintenance), so it is treated as expected and does not trigger normal escalation logic. Invalid indicates the alarm is not considered effective for operational follow-up— commonly used when a point is confirmed to be non-applicable, temporarily disabled, or its triggering condition is not meaningful to current operations. By contrast, Valid and Standard represent normal alarm handling states rather than outcomes specifically “identified by masking rules.”
For hourly statistics reports, data of up to how many days can be queried? For monthly statistics reports, data of up to how many years can be queried?
In Huawei NetEco statistical reporting, the query range is constrained by the report data retention policy and how summary data is stored. For hourly statistics, the platform keeps a limited window of high-granularity data to balance storage consumption and performance. The hourly report retention is 120 hours, which equals 5 days. That is why hourly statistics queries are limited to 5 days—beyond that window, hourly granularity is no longer retained in the report database for direct querying. For longer time horizons, NetEco relies on lower-granularity summaries (daily/weekly/monthly/yearly). For monthly statistics, the platform supports long-term trend analysis and KPI tracking, and the maximum historical horizon aligns with the long-term statistics retention boundary used by NetEco reporting, which is up to 5 years. This design ensures fast query response, manageable database growth, and clear separation between short-term operational detail (hourly) and long-term management analysis (monthly/yearly).
Video management can connect to the third-party video surveillance subsystem and play historical videos.
In Huawei’s data center O&M architecture, video is treated as an important auxiliary capability for security and remote operation. The Video Management function is designed not only to view live camera feeds, but also to integrate video resources into the same O&M workflow as alarms, access control events, and environmental monitoring. In typical deployments, the actual video storage and recording are handled by a third-party video surveillance subsystem (for example, an NVR/VMS platform). Huawei’s video management function can connect to that third-party subsystem so that camera resources can be accessed in a unified interface, allowing operators to perform linkage operations such as “view video on alarm” and routine security inspection without switching platforms. Because historical recordings are stored by the surveillance subsystem, once the integration is established and permissions are correctly configured, operators can retrieve and play back historical video for event tracing, audit, and incident investigation. This supports closed-loop O&M: alarm/event occurs →video verification →root-cause confirmation →maintenance action → evidence retention.
