Junos Telemetry Interface

  • Packet Forwarding Engine DDoS sensor support with JTI (EX4650, QFX5110, QFX5120-32C, QFX5120-48T, QFX5120-48Y, QFX5210 and QFX5200)—Starting in Junos OS Release 22.1R1, JTI supports distributed denial-of-service (DDoS) telemetry sensors. To stream DDoS statistics from a device to a collector, include the resource path /junos/system/linecard/ddos/) in a subscription. You can stream statistics using UDP (native) or Juniper proprietary gRPC and gNMI. This feature supports the Openconfig data model junos/ui/openconfig/yang/junos-ddos.yang.

    Currently, there are 45 packet types for DDoS. To maintain a reasonably sized data stream, data is exported for all protocols that have traffic using the zero-suppression model.
