This is the operating system software that powers a wide range of Cisco’s networking hardware, including routers, switches, and wireless controllers. It acts as the foundational software, managing hardware resources, implementing networking protocols, and providing the interface for administrators to configure and manage network devices. As an example, a network administrator might use this software to configure routing policies on a core router within a corporate network.
Its significance lies in its modular design and support for a wide array of features, enabling networks to scale and adapt to evolving business needs. It offers enhanced security features, improved network performance, and simplified management capabilities compared to earlier iterations. Historically, this software represented a significant shift towards a more open and programmable network infrastructure, allowing for easier integration with third-party applications and automation tools.
