Junos Telemetry Interface

  • OpenConfig sensor support for ZR and ZR+ optical transceivers on MPC10 line cards (MX2010 and MX2020)—Junos OS supports data streaming new leaves for ZR and ZR+ optics. You can create a subscription in INITIAL_SYNC or TARGET_DEFINED mode using Juniper's proprietary Remote Procedure Call (gRPC) service or gRPC Network Management Interface (gNMI). Use these resource paths in a subscription to stream data:
    • /components/component/transceiver/state/ new leaves fec-mode, fec-status, module-functional-type, fault-condition, fec-uncorrectable-blocks, and fec-corrected-bits
    • /components/component/transceiver/physical-channels/channel/state/ new leaves output-frequency and associated-optical-channel
    • /components/component/optical-channel/state/ leaves frequency and line-port
    This feature is based on data models openconfig-terminal-device.yang (version 1.8.0), openconfig-platform-transceiver.yang (version 0.8.0), and openconfig-transport-types.yang (version 0.14.0).

  • Backup next-hop group sensor support (MX960)—You can use this feature to send telemetry data for the backup next-hop group from your device to the collector. The feature supports streaming and ON_CHANGE subscriptions through Juniper's proprietary Remote Procedure Call (gRPC) or gRPC Network Management Interface (gNMI). Enable the feature by adding the backup-next-hop-group configuration statement at the [edit system fib-streaming model ocaft] hierarchy level.

    Removing this configuration disables the feature:

    [See Configuring Prefix Filtering, prefix-list, show fib-streaming state, and Junos YANG Data Model Explorer.]

  • Stream data from a device to a collector using basic Junos Telemetry Interface infra sensors and new component environment sensors— Junos OS supports these new sensors:

    Relative humidity sensor-

    Two input and one output dry contact sensors-

    You can also display the dry contact and relative humidity information using the operational mode commands show chassis environment and show chassis craft-interface.
