Support for in-band model-driven telemetry (MDT) data over gRPC

NCS6000 series routers support streaming telemetry on management interfaces. From Cisco IOS XR, release 7.2.1 and later, MDT can be streamed out-of-band using physical interfaces of the line cards on the router.

Release 7.2.1

gNMI TARGET_DEFINED subscription mode

Support for gNMI TARGET_DEFINED subscription mode.

Release 7.2.1

gRPC Network Management Interface

Support for streaming telemetry data at leaf-level
The router supports the following sensor-path resolutions:

  • For cadence-driven subscriptions, streaming data occurs at the leaf-level or at the container-level under a gather point

  • For event-driven subscriptions, streaming data is always at the gather point in the model, even if specific leaves or leaf is configured as sensor-path

Release 7.2.1

Sensor Path
JSON encoding support for gNMI Subscribe RPC

Cisco IOS XR routers support gNMI remote procedure calls (RPCs). The gNMI Subscribe RPC supports JSON encoding in addition to the previously supported PROTO encoding format.
