This specific release runs on the Cisco IOS XE dual-core architecture, which separates the data plane handling network traffic from the control plane running management applications. By containerizing processes, a glitch in a software feature will not take down the physical packet-switching infrastructure.

Cisco follows a structured naming convention for its IOS and IOS‑XE images. Understanding each field allows you to select the correct software for your hardware and avoid compatibility issues.
: Provides advanced routing features including BGP , OSPF , and EIGRP , though specific support (like BGP) requires the Enterprise Services license. Operational Considerations
Chassis with dual supervisor engines require a more carefully orchestrated sequence to maintain SSO (Stateful Switchover) operation.
