This release offers robust support for In-Service Software Upgrades (ISSU) on dual-supervisor configurations. It allows deployment of security patches and point releases without interrupting data-plane forwarding. Non-Stop Forwarding (NSF) and Stateful Switchover (SSO) work together to sync line cards during a supervisory failover in under 200 milliseconds. Advanced Security and Identity Integration
