- Implements FIPS 140-3 compliant encryption for control-plane communications
- Strengthened role-based access control (RBAC) policies for TACACS+ authentication
2. Protocol Stability Enhancements
- Fixes intermittent VXLAN EVPN route flapping in multi-pod ACI designs
- Improves BFD session stability during control-plane failovers
- Optimizes OSPFv3 convergence times by 40% in large-scale topologies
3. Hardware Compatibility Extensions
- Adds support for Nexus 9336C-FX2S line cards in ACI mode
- Enables full functionality of QSFP-100G-CR4 optics on 9500-R Series chassis
