- Dynamic NAT entry limits tied to real-time processor load
- Optimized synchronization for high-availability deployments
IPv6 Segment Routing Enhancements
Expanding on previous IOS XE capabilities, this version supports:
- IS-IS Topology-Independent LFA (Loop-Free Alternate)
- Micro-loop avoidance during IGP convergence events
- OAM integration for SRv6 traffic engineering
SD-WAN Optimization
Updates to the Catalyst SD-WAN implementation include:
- Multi-WAN interface support through custom VRF instances
- Flexible NetFlow v9 monitoring at flow granularity
- NWPI (Network-Wide Path Insight) diagnostics improvements
Security Updates
While specific CVEs aren’t listed in available documentation, the package includes:
- TLS 1.3 performance optimizations
- Enhanced credential management for Cisco Umbrella integration
- SGACL (Security Group Access Control List) logging via HSL
