Cisco NX-OS Upgrade License ESS to ADV

Advance Cisco NX-OS feature access without replacing the underlying switching platform. This SWSS upgrade license moves eligible environments from Essential to Advanced entitlement, giving infrastructure teams a cleaner path to the capabilities required for segmentation, policy control, and operational consistency across the network edge and core. For organizations running Cisco switching at scale, license alignment matters as much as hardware performance. This entitlement is designed for teams that need to expand software capability while maintaining a familiar Cisco support model through SWSS coverage. It fits procurement workflows where compliance, lifecycle planning, and predictable software access are part of the operating standard. Use it to bring existing deployments into a higher feature tier with minimal disruption to the installed base. The result is a more capable NX-OS environment that supports enterprise network requirements without forcing a platform migration.
