iMaster NCE-Campus embodies the core of Huawei’s Intent-Driven Network (IDN) solution. Its principal advantage is the paradigm shift from managing boxes (devices) to managing business intents, users, and services. This allows for automation, policy-based management, and much faster service provisioning, which directly addresses the client’s needs for reliability and agility.

Microbursts are short, intense traffic bursts that happen in milliseconds, far faster than traditional SNMP polling intervals (e.g., 5 minutes). Telemetry provides a mechanism for devices to push high-precision, real-time data (like interface counters at sub-second intervals) to a collector. This granular data is essential for visualizing and diagnosing microbursts, which would be invisible in average utilization statistics.

SR-MPLS TE Policy allows for the creation of explicit paths that are independent of the IGP shortest path. By constructing a path using a list of adjacency SIDs (which represent specific links), you can engineer a route that precisely avoids the prohibited geographical region. This provides deterministic path control, which is not possible with SR-MPLS BE or a simple ACL filter.

The centralized gateway model, where the Layer 3 gateway function resides on a few spine nodes (or dedicated appliances), can create a traffic tromboning effect. East-west traffic between servers in the same subnet but on different leaf switches must travel up to the centralized gateway and back down, increasing latency and load on the spines. Distributed gateways, where the Layer 3 function exists on every leaf, provide optimal any-to-any connectivity and are generally preferred for modern, scalable data centers.

A high “Air Interface Usage” metric directly points to congestion in the radio frequency (RF) environment. This is typically caused by too many devices contending for airtime or co-channel interference from other Wi-Fi networks. The proactive step, guided by NCE-CampusInsight, would be to analyze the RF environment, identify congested channels, and potentially execute a channel and power adjustment (CPC) plan to optimize the layout, not assume hardware failure first.

A sampling rate of 1 means every packet is sampled, resulting in the export of a record for every flow. This is “full collection” and provides 100% accurate flow data, capturing all conversations and packet counts. It is the most detailed option but generates the highest volume of export data, which is acceptable if the collector can handle it, as stated in the scenario.

This is a classic use case for EVPN VXLAN with VRFs (Virtual Routing and Forwarding). A new Bridge Domain (BD)/VXLAN segment provides Layer 2 isolation. The associated VRF provides a completely separate Layer 3 routing table for the partner. Policies (ACLs, QoS) can be applied at the ingress leaf switch (distributed gateway), ensuring secure, controlled, and optimal access without hair-pinning traffic through a central choke point.

The core value of BFD is its role as a dedicated, fast failure detection service. Routing protocol hellos are often too slow (e.g., 10-second intervals). BFD establishes a separate, lightweight session that sends rapid, low-overhead control packets. When it detects a failure, it quickly notifies its “client” protocols (OSPF, BGP, etc.), allowing them to trigger convergence in milliseconds or seconds, rather than tens of seconds.

Application-Aware Routing (AAR) is a key SD-WAN intelligence feature. It continuously monitors the performance (latency, jitter, loss) of multiple underlay tunnels (like Internet and MPLS). Based on predefined policies (e.g., “if loss > 1% for VoIP, switch tunnel”), it can dynamically steer specific application traffic to the best-performing path in real-time, optimizing user experience automatically.
