Release Notes for Cisco Enterprise Network Function Virtualization Infrastructure Software, Release 3.7.x

About Cisco Enterprise NFVIS

Cisco Enterprise Network Function Virtualization Infrastructure Software (Cisco Enterprise NFVIS) is a Linux-based infrastructure software designed to help service providers and enterprises dynamically deploy virtualized network functions, such as a virtual router, firewall, and WAN acceleration, on a supported Cisco device. There is no need to add a physical device for every network function, and you can use automated provisioning and centralized management to eliminate costly truck rolls.

Cisco Enterprise NFVIS provides a Linux-based virtualization layer to the Cisco Enterprise Network Functions Virtualization (ENFV) solution.

Cisco ENFV Solution Overview

Cisco ENFV solution helps you convert your critical network functions into software, making it possible to deploy network services in minutes across dispersed locations. It provides a fully integrated platform that can run on top of a diverse network of both virtual and physical devices with the following primary components:

  • Cisco Enterprise NFVIS

  • VNFs

  • Unified Computing System (UCS) and Enterprise Network Compute System (ENCS) hardware platforms

  • Digital Network Architecture Center (DNAC)

For more details on the Cisco ENFV solution, see the Cisco Enterprise Network Functions Virtualization Solution Overview.

System Requirements

The following resources are required for a standalone Cisco Enterprise NFVIS:

  • One CPU core

  • 2 GB RAM

  • 20 GB storage


Note

More memory and disk space are required to be added to the system, depending on VM deployments.


Supported Programs and Platforms for Cisco ENFV

The Cisco ENCS 5400 Series and UCS E-Series platforms ship with multiple firmware binaries that are inter-dependent on the corresponding NFVIS releases. When these platforms are ordered, Cisco ships them with the right combination of software. Special care must be taken while upgrading from NFVIS 3.6.x to 3.7.x.

Please be aware of the following BIOS restrictions:
  • NFVIS 3.7.1 supports all ENCS5400 BIOS versions from 1.2 through 2.4.

  • Version 2.3 or above is required if you are using a hardware RAID card.

  • Note that version 2.3 or above are not compatible with NFVIS 3.5.1. Upgrading to BIOS 2.3 or above on a system running NFVIS 3.5.1 may cause the install to fail and require reinstallation after downgrading the BIOS.

  • To upgrade your ENCS 5400 BIOS to 2.3 or above, ensure you upgrade NFVIS to 3.6.1 or later first, before upgrading the BIOS.

  • Please refer to the Supported Platforms and Firmwaresection of the Release Notes and ensure your platform has the supported BIOS, CIMC, and other firmware versions applied.


Note

If a newer HUU is applied on older NFVIS versions, the system may not boot up. To recover from this situation, downgrade the BIOS to the older version, or reinstall NFVIS. The latter will result in user data loss.

Open and Resolved Bugs

The open and resolved bugs for a release are accessible through the Cisco Bug Search Tool. This web-based tool provides you with access to the Cisco bug tracking system, which maintains information about bugs and vulnerabilities in this product and other Cisco hardware and software products. Within the Cisco Bug Search Tool, each bug is given a unique identifier (ID) with a pattern of CSCxxNNNNN, where x is any letter (a-z) and N is any number (0-9). The bug IDs are frequently referenced in Cisco documentation, such as Security Advisories, Field Notices and other Cisco support documents. Technical Assistance Center (TAC) engineers or other Cisco staff can also provide you with the ID for a specific bug. The Cisco Bug Search Tool enables you to filter the bugs so that you only see those in which you are interested.

In addition to being able to search for a specific bug ID, or for all bugs in a product and release, you can filter the open and/or resolved bugs by one or more of the following criteria:

  • Last modified date

  • Status, such as fixed (resolved) or open

  • Severity

  • Support cases

You can save searches that you perform frequently. You can also bookmark the URL for a search and email the URL for those search results.
