Introduction to Sightline_9.3.1.zip

This Cisco IOS XR analytics enhancement package provides advanced network visibility tools for ASR 9000 Series routers operating in hyperscale carrier networks. Designed for operators requiring predictive maintenance capabilities, the “Sightline_9.3.1” release integrates machine learning-driven traffic pattern analysis with Cisco Crosswork Network Controller ecosystems.

The software bundle contains optimized YANG data models, telemetry collectors, and API extensions compatible with IOS XR 9.3.1+ environments. Released under Cisco’s 2025 Q2 Software Advisory (CSCwi78903), it specifically addresses operational gaps in segment routing traffic engineering (SR-TE) diagnostics. Compatible hardware includes ASR 9904/9910/9920 chassis equipped with Cisco Silicon One Q250 processors and 800G-capable line cards.
