Cisco Enterprise NFVIS, Release 26.1.1
Cisco Enterprise NFVIS, Release 26.1.1
This release introduces significant accessibility upgrades designed to create a more inclusive user experience. Key updates include improved keyboard navigation and focus order, enhanced screen reader support through updated ARIA roles, and full compliance with WCAG 2.1 AA color contrast standards. Additionally, the update provides descriptive alternative text for all visual elements and optimizes form control structures to ensure seamless compatibility with assistive technologies.
Note: Rebranding: To achieve simplification and consistency, the Cisco SD-WAN solution has been rebranded as Cisco Catalyst SD-WAN. In addition, from Cisco IOS XE SD-WAN Release 17.12.1a and Cisco Catalyst SD-WAN Release 20.12.1, the following component changes are applicable: Cisco vManage to Cisco Catalyst SD-WAN Manager, Cisco vAnalytics to Cisco Catalyst SD-WAN Analytics, Cisco vBond to Cisco Catalyst SD-WAN Validator, Cisco vSmart to Cisco Catalyst SD-WAN Controller, and Cisco Controllers to Cisco Catalyst SD-WAN Control Components.
See the latest Release Notes for a comprehensive list of all the component brand name changes. While we transition to the new names, some inconsistencies might be present in the documentation set because of a phased approach to the user interface updates of the software product.
Cisco is constantly enhancing the Cisco Enterprise Network Function Virtualization Infrastructure Software with every release, and we try and keep the content in line with the latest enhancements. The following table lists new and modified features we documented in the Configuration, Command Reference, and Hardware Installation guide.

Migrating from Insecure to Secure Configuration |
Starting from SD-WAN Manager 26.1.1, Cisco introduces the system mode insecure CLI command. This command is required if your configuration contains insecure features (such as SNMPv1/v2, HTTP, or weak ciphers). To move a device to a fully secure state, you must correct the insecure configurations and then transition the device mode from "Insecure" to "Secure." For more information, refer to Migrating from Insecure to Secure Configuration, Release 26.1.1 Resilient Infrastructure, a Cisco initiative to strengthen network security, introduces advanced security capabilities that reduce the attack surface and enable better detection and response. For more information, see Resilient Infrastructure. |

Non-Cisco Vendor Owned VNFs
You can run VNFs owned by various vendors on Cisco’s NFV platforms enabled by NFVIS . Formal support for these VNFs requires a joint effort between Cisco and the VNF vendor.
Cisco offers VNF vendors a "for-fee" NFVIS 3rd-party certification program to test and certify their VNFs on Cisco’s virtualized platforms. After testing and certification is complete, the results are published on this page-
For more specific support details about VNF versions and test compatibility matrix with NFVIS releases, see the VNF release documentation on the vendor support site.
As a NFVIS customer, if you need a unique combination of NFVIS release and a specific VNF version, you may submit your certification request to Cisco at nfv-ecosystem@cisco.com or reach out to the VNF vendor support team asking them to initiate a certification on the Cisco platform.
