In Huawei's data center facility management architecture, the northbound interface of NetEco is designed specifically to integrate with upper-layer systems such as enterprise NMS platforms, SOC/monitoring centers, and customer unified O&M systems. To meet common industry integration practices, NetEco northbound capabilities are not limited to only one interface type. In addition to WebService-style interfaces used for richer data exchange and structured integration, NetEco also supports SNMP-based northbound integration, which is widely used for alarm forwarding, basic status monitoring, and interoperability with standard network management tools. SNMP is particularly common in mixed-vendor environments because it enables a lightweight and standardized method to deliver key alarms and events to a customer's central monitoring platform without requiring deep application coupling. Therefore, the statement that
"only WebService interfaces are supported and SNMP is not supported" is incorrect: NetEco northbound integration supports SNMP along with other northbound interface methods depending on the integration scenario and customer requirements.
