Feature 

Description

Software Reliability

Configurable pod anti-affinity for policy engine pods

This feature supports configurable anti-affinity for Policy Engine pods, allowing operators to choose between strict and relaxed modes. This enhancement improves pod placement efficiency and resource utilization, especially in environments with limited nodes or high CPU density, while preserving high availability as the default behavior.

Software Reliability

PCF-based QoS boost validity timers

This enhancement introduces support for time-bound and priority-based QoS boost profiles for subscribers, enabling dynamic control of APN-level AMBR and 5QI through configured validity timers. Operators can provision multiple QoS schedules per subscriber, each with explicit start and end times, allowing temporary QoS uplift and automatic reversion to the previously active profile upon expiry.

The PCF evaluates configured schedules and applies the appropriate QoS profile to active and newly established sessions, ensuring deterministic behavior across Gx and N7 interfaces.

Ease of use

Deploy database monitoring dashboard

You can enable or disable the deployment of a specific DB Monitoring dashboard (Grafana JSON) by setting a configuration value. As a result, the dashboard is deployed only when needed, which optimizes resource usage and provides critical insights into database health and usage.

The Database Monitoring Dashboard provides dedicated monitoring capabilities for key PCF data stores, such as MongoDB replica sets.

Command Introduced: testing enable-optional-dashboards [true| false].

Changes in behavior

There are no behavior changes introduced in this release.

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.

Software integrity version

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.

Figure 2.              Sample of PCF Software Image

A close up of a documentAI-generated content may be incorrect.

 

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

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

To calculate a SHA512 checksum on your local desktop, see this table.

Table 6.                 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>

Note:       <filename> is the name of the file. <extension> is the file type extension (for example, .zip or .tgz).

If the SHA512 checksum matches, you can be sure that no one has tampered with the software image or the image has not been corrupted during download.

If the SHA512 checksum does not match, we advise you to not attempt upgrading any systems with the corrupted software image. Download the software again and verify the SHA512 checksum again. If there is a constant mismatch, please open a case with the Cisco Technical Assistance Center.

Certificate validation

PCF software images are signed via x509 certificates. Please view the README file packaged with the software for information and instructions on how to validate the certificates.
