Understanding IS-IS Subscribe Configuration

Overview

You can access the segment-routing or spring sensor-based traffic statistics stored in the Packet Forwarding Engine using the sensor ID on the FPC command line. Accessing each FPC to fetch the traffic statistics involves multiple task.

You can now easily record the recent spring sensor-based traffic statistics at the [edit protocols isis source-packet-routing] hierarchy level. Use the following set configuration statements to trigger the on-box spring sensor subscription process and record detailed sensor-based traffic statistics.

The spring sensor-based subscribe configuration creates a connection with network-agent and subscribes to the configured sensor path. The sensor path is installed in the Packet Forwarding Engine where the telemetry sensor-based data is stored. The telemetry process keeps track of the latest updates received on each subscribed sensor. The show spring traffic statistics command displays the traffic statistics information streamed from the Packet Forwarding Engine.
