Configure Routers to Send JTI Telemetry Data and RPM Statistics to the Data Collector

Junos Telemetry Interface (JTI) sensors generate data (LSP traffic data, logical and physical interface traffic data) from the Packet Forwarding Engine (PFE), and will only send probes through the data plane. So, in addition to connecting the routing engine to the management network, a data port must be connected to the collector on one of your devices. The rest of the devices in the network can use that interface to reach the collector.


You must use Junos OS Release 15.1F6 or later for the analytics feature.

To configure the routers, use the following procedure:

  1. Configure the devices for telemetry data. On each device, the following configuration is required. The device needs to be set to enhanced-ip mode, which might require a full reboot.

    Use default remote-port 4000 and set the remote-address to the Paragon Insights virtual IP address.

    In this configuration, the remote address is the IP address of the collector (reachable though a data port). The local address should be the loopback, or router-id, whichever is configured on the device profile to identify the device.

  2. Bandwidth sizing and container LSPs are supported for SR-TE LSPs. Junos OS release 19.2R1 or later is required for this functionality. There is additional configuration required on the router to enable collection of segment routing data. For example:
  3. Real-time performance monitoring (RPM) enables you to monitor network performance in real time and to assess and analyze network efficiency. To achieve this, RPM exchanges a set of probes with other IP hosts in the network for monitoring and network tracking purposes.

    You must configure RPM probes to measure the interface delays.

    The following example shows the configuration of probes out of interface ge-0/1/1.0 to the remote address This remote address should be the IP address of the node at the other end of the link.


    The test name must match the interface being measured (test ge-0/1/1.0, in this example).
