What's New in this Release

Features and Enhancements

This section covers a brief description of the features and enhancements introduced in this release. It also includes links to detailed documentation, where available.

Feature Description

Diameter Traffic Performance Optimization

This release introduces new configuration options to enhance the performance of Diameter pods when processing Diameter messages. These options allow for tuning Istio concurrency based on the user's traffic profile.

Commands introduced:

advance-tuning istio-resource-control diameter - This CLI command configures the Istio-proxy in the diameter-ep pod.

diameter properties <grpc-tcp-nodelay> value {false | True} - The grpc-tcp-nodelay option in this CLI command controls the Nagle algorithm for TCP transmission. By enabling this command, you can reduce the latency and prevent delays in sending small packets, thus optimizing real-time data transmission.

Default Setting: Disabled – Configuration Required to Enable

SPR MongoDB Deployment in PCF Namespace

This feature involves the integration of MongoDB replica sets into the PCF namespace on a Kubernetes (K8s) cluster. It supports various operations like storing, retrieving, and updating subscriber data.

The PCF ops-center and policy builder page manage the configuration of the MongoDB replica sets.

Default Setting: Disabled – Configuration Required to Enable

Behavior Changes

There are no behavior changes in this release.

Installation and Upgrade Notes

This Release Note does not contain general installation and upgrade instructions. Refer to the existing installation documentation for specific installation and upgrade considerations.

Software Integrity Verification

To verify the integrity of the software image you have from Cisco, you can validate the SHA512 checksum information against the checksum identified by Cisco for the software.

Image checksum information is available through Cisco.com Software Download Details. To find the checksum, hover the mouse pointer over the software image you have downloaded.

At the bottom, you will find the SHA512 checksum. If you do not see the whole checksum, you can expand it by pressing "..." at the end.

To validate the information, calculate a SHA512 checksum using the information in Table 1 and verify that it matches either the one provided on the software download page.

To calculate a SHA512 checksum on your local desktop, refer to the following table.

Table 1. Checksum Calculations per Operating System

Operating System

SHA512 checksum calculation command examples

Microsoft Windows

Open a command line window and type the following command:

> certutil.exe -hashfile filename.extension SHA512

Apple MAC

Open a terminal window and type the following command:

$ shasum -a 512 filename.extension

Linux

Open a terminal window and type the following command:

$ sha512sum filename.extension

OR

$ shasum -a 512 filename.extension

NOTES:

filename is the name of the file.

extension is the file extension (for example, .zip or .tgz).

Certificate Validation

Operator Notes

Cloud Native Product Version Numbering System

The show helm list command displays detailed information about the version of the cloud native product currently deployed.

The appropriate version number field increments after a version has been released. The new version numbering format is a contiguous sequential number that represents incremental changes between releases. This format facilitates identifying the changes between releases when using Bug Search Tool to research software releases.
