Cisco NX-OS Upgrade License ESS to ADV Modular 4 Slot

Expand feature access on supported modular Cisco platforms with an Essentials-to-Advanced NX-OS upgrade license for four slots. This entitlement is built for infrastructure teams that need more from the same chassis investment: broader software capability, cleaner license alignment, and a path to advanced operational features without a hardware refresh. For environments where platform longevity matters, the right license tier can be the difference between staying constrained and meeting new network requirements. This upgrade license helps move eligible modular systems into the Advanced feature set, supporting more demanding data center and campus networking needs while preserving the installed base. Because it is tied to a specific 4-slot modular entitlement, it fits controlled procurement and standardized deployment models. That makes it easier to track licensing across assets, maintain consistency in configuration planning, and justify software spend against the value of extended platform capability.
