Introduction to n7700-s2-dk9.7.3.3.D1.1.bin Software

The ​​n7700-s2-dk9.7.3.3.D1.1.bin​​ is the primary NX-OS software image for Cisco Nexus 7700 Series switches with Supervisor 2T modules, delivering enhanced Layer 3 routing capabilities and VXLAN EVPN multi-site orchestration. This release introduces hardware-assisted telemetry streaming for data center fabric monitoring and implements Cisco’s TrustSec enhancements for software-defined segmentation.

Compatible with N77-C7710/7718 chassis configurations, the software supports 100G/400G line cards including N77-F424XP-23 and N77-F412CK-26 models. Cisco’s release notes confirm full interoperability with ACI 5.3(1)+ fabrics when using MPLS-over-VXLAN encapsulation.

Key Features and Improvements

Version 9.7(3) introduces:

  1. ​​Hardware Resource Optimization​​ – 30% improvement in TCAM utilization for IPv6 ACL policies
  2. ​​Telemetry Enhancements​​ – gRPC dial-out streaming at 50ms intervals for real-time buffer monitoring
  3. ​​Security Hardening​​ – TPM 2.0-based secure boot validation for supervisor modules
  4. ​​Protocol Support​​ – BGP-LS extensions for segment routing traffic engineering
  5. ​​Fabric Stability​​ – Resolved CRC error accumulation on N77-M312FQ-25L line cards

Technical documentation highlights improved ISSU (In-Service Software Upgrade) success rates during multi-protocol migrations and enhanced FEX offline diagnostics.
