In iMaster NCE-Campus, device management functions are tightly integrated with secure remote access mechanisms to ensure safe and efficient O&M operations. One such mechanism is theSSH proxy tunnel, which allows administrators to remotely access managed devices through the controller without directly exposing device management interfaces to the external network.

According to HCIP Datacom Campus Network documentation, theSSH proxy tunnel is automatically established when the Command Line function is usedon the Device Management page. When an administrator clicks theCommand Lineoption, iMaster NCE-Campus dynamically builds a secure SSH proxy channel between the controller and the target device. This enables real-time CLI access to the device through the web interface while maintaining strict security controls.

Other functions such asSummary,Entry Query, andDevice Configurationdo not require direct CLI interaction with the device. These functions rely on management protocols and configuration delivery mechanisms such as NETCONF or telemetry, and therefore do not trigger the establishment of an SSH proxy tunnel.

The Command Line function is specifically designed for scenarios such as advanced troubleshooting, manual verification, or executing device-level commands. Automatically enabling the SSH proxy tunnel at this moment ensures that CLI access is bothsecure and on-demand, reducing attack surfaces and simplifying remote maintenance.

Therefore, the function that automatically enables the SSH proxy tunnel isCommand Line, making optionDthe correct answer.

In anasymmetric IRB (Integrated Routing and Bridging)VXLAN forwarding model, Layer 2 forwarding and Layer 3 routing occur ondifferent VTEPs. When PC1 sends traffic to PC2, the packet is first forwarded to thelocal gateway (VBDIF interface)on VTEP1 for Layer 3 routing.

After routing is performed, VTEP1 encapsulates the packet into a VXLAN packet and forwards it to VTEP2. Importantly, theoriginal data frame inside the VXLAN packethas already been rewritten after routing. The destination MAC address in the original Ethernet frame is no longer the MAC address of PC2, but theMAC address of the next-hop gateway on the remote VTEP.

In the figure, this next-hop MAC address isMAC C, which belongs to the VBDIF interface on VTEP2. MAC D (PC2’s MAC address) is only used after the packet is decapsulated and forwarded locally by VTEP2.

According to HCIP Datacom Campus Network VXLAN forwarding behavior, the correct destination MAC address of the original data frame sent from VTEP1 to VTEP2 isMAC C, making optionCcorrect.

iMaster NCE-Campus adopts a flexiblemulti-plane networking architectureto meet different deployment scale and reliability requirements. According to HCIP Datacom Campus Network documentation, iMaster NCE-Campus supports bothsingle-plane networkingandmulti-plane networking, and the selection depends on the system deployment mode.

In asingle-node system deployment, all functional components of iMaster NCE-Campus run on a single node. In this scenario,single-plane networking is optionaland can be used to simplify network planning and reduce deployment complexity. Management traffic, service traffic, and internal communication share the same network plane, which is sufficient for small-scale or test environments where high availability and strict isolation are not mandatory.

However, inmulti-node or cluster deployments, iMaster NCE-Campus requiresmulti-plane networking. Different network planes—such as management plane, service plane, and internal communication plane—are deployed separately to ensure high availability, scalability, performance isolation, and security. Single-plane networking isnot supportedin these deployments because it cannot meet the reliability and performance requirements of clustered systems.

This design ensures that large-scale campus networks benefit from fault isolation and load separation, while smaller deployments can use a simplified architecture. Therefore, the statement that single-plane networking is optional only in single-node system deployment is consistent with HCIP Datacom Campus Network design principles.

Hence, the correct answer isTRUE.
