Junos Telemetry Interface

  • Telemetry support for interfaces and chassis (EX2300, EX2300-MP, EX2300-C, EX2300-VC, EX3400, EX3400-VC, EX4100-MP, EX4100-F, EX4300-MP, EX4400-MP, EX4400, EX4650, QFX5110, QFX5120, QFX5200, and QFX5210)—Junos OS Release 22.4R1 introduces support for streaming operational state statistics and counters for chassis and interfaces using OpenConfig sensor paths. We also support the following new Junos-specific sensor paths for statistics that are unsupported in OpenConfig:

    • /state/chassis/

    • /state/interfaces/

    [See Telemetry Sensor Explorer.]

  • Support for gRPC tunnel sessions (MX204, MX240, MX480, MX960, MX10003, MX10004, MX10008, MX10016, MX2008, MX2010, MX2020, PTX-5000, PTX1000, PTX10002, VMX, and QFX5110)—Starting with Junos OS Release 22.4R1, you can configure a gRPC tunnel session to establish a connection between an external TCP client and a TCP server. The gRPC tunnel session establishes a reverse connection when a TCP client can't reach the TCP server.

    To establish a gRPC tunnel session, include the grpc-tunnel configuration statement in the [edit system services] hierarchy.

    [See gRPC Tunnels Overview.]
