About Cisco Enterprise NFVIS

Note

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.

What's New

New and Enhanced Features for Cisco Enterprise NFVIS Release 4.9.6

Feature

Description

BIOS Upgrade for C8200 UCPE

Starting from the Cisco NFVIS 4.9.6 release, this feature outlines the BIOS upgrade process for the Cisco Catalyst 8200 Series Edge uCPE device to resolve the random number generation issue. This upgrade includes updates to Secure Boot FPGA and BIOS capsule.

New and Enhanced Features for Cisco Enterprise NFVIS Release 4.9.3

Feature

Description

Change in default system memory for CSP devices

Starting from Cisco NFVIS 4.9.3 release, 8 GB is allocated to Cisco NFVIS in a CSP device with 64 GB memory space.

A new command to clear cache memory

The support flush cache memory command is introduced to clear cache memory using the CLI, that clears up some system memory to enable Cisco NFVIS to perform better. Clearing caches using support flush cache command can help resolve issues related to outdated or corrupted cache data. For example, clearing the cache in a web browser can help resolve issues such as slow page load times of Cisco NFVIS portal.

New and Enhanced Features for Cisco Enterprise NFVIS Release 4.9.1

Feature

Description

Cisco NFVIS Kubernetes Support

This feature enables you to deploy and operate Kubernetes as a VM using Cisco Enterprise NFVIS. You can download the NFVIS Kubernetes.tar.gz file, upload it to the Cisco Enterprise NFVIS and deploy the Kubernetes VM to leverage Kubernetes related technologies within Cisco Enterprise NFVIS.

VM Image Packaging Tool

The VM image packaging tool provides the UI for you to generate a full VM package, generate a scaffold package, and repackage. The tool works separately from the Cisco NFVIS system.

Resolved and Open Bugs

About the Cisco Bug Search Tool

Use the Cisco Bug Search Tool to access open and resolved bugs for a release.

The tool allows you to search for a specific bug ID, or for all bugs specific to a product and a release.

Important Notes

In Cisco NFVIS 4.6.1, backup with GE0-1-SRIOV-3 cannot be restored on ENCS 5400. For more details, see CSCvz82738.

Cisco NFVIS 4.7.1 is the last release in which the system settings dns-server command is supported. We recommend that you use the system settings name-server command (supported from NFVIS 4.4.1) instead of system settings dns-server, starting from NFVIS 4.8.1 and later releases.

Cisco NFVIS 4.7.1 is the last release in which the route-distribute command is supported. We recommend that you use the router bgp command, instead of route-distribute, starting from Cisco NFVIS 4.8.1 and later releases. For more information on the router bgp command, see Configure BGP on NFVIS.

Starting from Cisco NFVIS 4.7.1 and later releases, we recommend that you use the .iso file upgrade method to upgrade NFVIS. For more information on upgrading Cisco NFVIS, see Upgrade Cisco NFVIS.

Starting from Cisco NFVIS 4.9.1 release, The memory reserved for Multi-NUMA node systems with more than 128 GB is increased to 20 GB in total. The memory reserved for Multi-NUMA node systems with more than 64 GB is increased to 10 GB in total.

Cisco NFVIS 4.8.1 is the last release in which .nfvispkg file is published for upgrading the Cisco NFVIS devices.

Starting from Cisco NFVIS 4.9.1 and later releases, use the .iso file upgrade method to upgrade NFVIS. For more information on upgrading Cisco NFVIS, see Upgrade Cisco NFVIS.

If your Cisco NFVIS devices are running Cisco NFVIS Release 4.6.x and you are looking to upgrade to NFVIS Release 4.9.x using direct upgrade, we recommend that you use the Cisco-4.9.1-FC3.iso software image instead of Cisco-4.9.1-FC2.iso software image for a stable user experience.

If your Cisco NFVIS devices are running Cisco NFVIS Release 4.9.1, upgraded using the Cisco-4.9.1-FC2.iso image, we recommend that you upgrade to Cisco-4.9.1-FC3.iso version of the software for a stable experience.

Cisco NFVIS 4.9.x is the last supported Cisco NFVIS release for the following device platforms:

CSP-5216

CSP-5228

CSP-5436, CSP-5444, and CSP-5456

Starting from Cisco NFVIS 4.9.3 release, 8 GB is allocated to Cisco NFVIS in a CSP device with 64 GB memory space.

If you are using I-350 based Network Interface Cards (NICs) that use IGB drivers, the Virtual Router Redundancy Protocol (VRRP) is not supported due to a limitation of MAC addresses that can be used in your network.

Software Upgrade

The Cisco Enterprise NFVIS upgrade image is available as .iso file. Currently, downgrades are not supported.

For more details on the software upgrade, see the Upgrading Cisco Enterprise NFVIS section in the Cisco Network Function Virtualization Infrastructure Software Getting Started Guide.

For a system that has 16 or less CPU cores, one CPU core is reserved for NFVIS. For a system that has more than 16 CPU cores, 2 CPU cores are reserved for NFVIS.

For a system that has 32 GB or less of RAM, 3 GB is reserved for NFVIS. For a system that has more than 32 GB of RAM, 4 GB is reserved for NFVIS.

20 GB storage.

For NFVIS portal, the minimum supported version of browsers are:

Mozilla Firefox 66

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- Cisco Enterprise NFV Open Ecosystem and Qualified VNF Vendors.

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.
