​​Introduction to Sightline_9.3.5.zip​​

This software package delivers Cisco Network Analytics Suite version 9.3.5 for Nexus 9000 Series switches, designed for enterprise network operators requiring granular visibility into data center fabric performance. Originally released in Q3 2024, the “_9.3.5” build introduces enhanced telemetry capabilities for monitoring 400G QSFP-DD interfaces while maintaining backward compatibility with N9K-C9336C-FX2 and N9K-C9508-FM-E chassis configurations.

The “Sightline” designation indicates integration with Cisco’s Crosswork Network Controller architecture, providing predictive analytics for VXLAN/EVPN overlays and hardware resource utilization diagnostics. Compatible with both standalone and ACI-mode deployments, this ZIP archive contains Python-based automation scripts, MIB files, and JSON schema templates for custom dashboard creation.
