The IOS feature set for routing and switching is unmatched in the industry, delivering functionality
required for business critical applications. Preserving these advantages of IOS to our customers is
critical for Cisco. IOS XE retains the exact same look and feel of IOS, while providing enhanced
future-proofing and improved functionality. In IOS XE, IOS 15.0 runs as a single daemon within a
modern Linux operating system. Additional system functions now run as additional, separate
processes in the host OS environment. The operation, support and management of IOS XE does
not require re-training from classic IOS.
