The Cisco Nexus 7000 Series Scalable Feature license provides the flexibility to enable the XL capabilities without requiring a hardware module change or upgrade. A single license per system enables all XL-capable I/O modules to operate in XL mode. After the single system license is added to a system, all modules that are XL capable are enabled with no additional licensing.
The software feature license reduces the operational challenges associated with having unique hardware requirements for systems that require larger forwarding tables and helps ensure that investment protection continues into the future regardless of deployment scenarios.
This license offers several advantages. It offers capital cost savings through operation in an environment in which a common hardware module can be used in all places in the network, regardless of whether the large or standard table size is appropriate. It also enables reduced operational costs through simplification of the effort associated with qualifying multiple different hardware types, software testing, and configuration management because all features not specifically increased by the feature license remain consistent. The system license can be added as needed to enable the larger tables in specific systems, and the use of common hardware simplifies sparing and maintenance.
Ease of sparing
Use of a single common hardware base reduces the need to stock multiple versions of a module in depots and in partner and customer environments.
Upgrade in place
Customers can defer costs, using the flexible chassis license to upgrade an entire system when needed without a requirement to upgrade the hardware or replace the modules.
Customers can purchase one module with the knowledge that should they later need to use larger forwarding tables, either because of a change in design or scaling, the hardware is ready.
The same module can be deployed in all environments and configured correctly, either with or without the license to enable the incremental feature.
