Question

You are designing a model-driven telemetry solution for a data center fabric. The operations team wants near-real-time notification whenever an interface operational status transitions (up/down), but they want to minimize the volume of redundant telemetry data sent when interfaces are stable for long periods. Which subscription configuration best meets these requirements?

Accepted Answer

An on-change subscription on the interface oper-status sensor path

Answer

A periodic (sample-interval) subscription with a 1000 ms cadence on the interface state sensor path

Answer

A periodic subscription with a 60000 ms cadence combined with SNMP trap fallback

Answer

A dial-in subscription that the collector polls every 5 seconds via gRPC
