Application Scenarios for NETCONF
Application Scenario of the NETCONF over SSH Callhome Mode
In the Huawei CloudCampus Solution, switches are deployed at the access or aggregation layer of a campus network for data forwarding. In contrast with switches that have NETCONF disabled, NETCONF-enabled switches are plug-and-play and can automatically register with iMaster NCE-Campus over the Internet for zero touch deployment. Additionally, NETCONF-enabled switches support configurations delivered by iMaster NCE-Campus anytime, anywhere, achieving fast batch service configuration.
In Figure 1, the egress gateway also functions as a DHCP server, which is configured with Option 148 containing the NETCONF enabling configuration and iMaster NCE-Campus's address information. Using DHCP, switches can automatically enable the NETCONF function, obtain the iMaster NCE-Campus's address information, and become plug and play. This networking applies to the enterprise-built cloud platforms that are not connected to the registration query center.
In Figure 2, the registration query center is deployed in the Huawei CloudCampus Solution. iMaster NCE-Campus synchronizes the device information imported by administrators to the registration query center in real time. Switches then send requests to the registration query center, automatically enable the NETCONF function, obtain the iMaster NCE-Campus's address information, and become plug and play. This networking applies to the Huawei public cloud platform, MSP-built cloud platforms, and enterprise-built cloud platforms that are connected to the registration query center.
Application Scenario of the NETCONF over SSH Mode
Using NETCONF, third-party NMSs can provide unified network management through a GUI and improves the security, reliability, and scalability of device management. In Figure 3, the NMS sets up NETCONF sessions with all switches on the network. The administrator can manage these switches on the GUI provided by the NMS to improve O&M efficiency.
