  2. ​Protocol Optimization​
    • Improves BGP convergence time by 30% in full-mesh topologies
  3. ​Hardware Support​
    • Adds official compatibility with N77-M348XP-23L modules
  4. ​Energy Efficiency​
    • Implements dynamic power scaling reducing PSU load by 15%
  5. ​Management Enhancements​
    • Expands NETCONF/YANG model coverage for automation workflows

Compatibility and Requirements

Supported Hardware

Component Minimum Requirement
Chassis Models Nexus 7718/7710/7706
Supervisor N77-SUP2E (VID 2.0+)
Line Cards N77-F348XP-23P/-23L

System Requirements

  • ​Bootflash Storage​​: 64GB+ per supervisor
  • ​Kickstart Image​​: n7700-s2-kickstart.6.2.22.bin
  • ​EPLD Version​​: 6.0.4+ for fabric modules

Secure Software Access

Network administrators requiring ​​n7700-s2-dk9.6.2.22.bin​​ should:

  1. Visit IOSHub for MD5-validated packages
  2. Enterprise customers with Smart Licensing can obtain via Cisco Software Center
  3. Submit TAC case with active service contract for emergency distribution

Critical Note: Always maintain version parity between kickstart and system images. Mismatched versions will prevent successful boot operations.
