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 | ||
|---|---|---|---|
|
AMF now supports deploying a single AMF instance across a four-server configuration using M5 servers. This setup includes three master servers and one worker server. This deployment provides an enhanced scalability and reliability with the AMF instance distributed across the available M5 servers. |
|||
|
This feature allows the AMF to interact with EIR to validate the UE identity during the UE registration procedure. EIR check enhances the network management by tracking and managing the status of the devices. Command introduced: eir-check { enabled | emergency-registration | deny-greylisted | initial-registration } Default Setting: Disabled – Configuration Required |
|||
|
AMF supports the storage of the EDR files in the EDR monitor pods. You can use the EDR files for debugging and troubleshooting. Command introduced: edr reporting { enable [ all subscribers | file [ transaction | transaction-collision ] ] | disable file [ transaction | transaction-collision ] } Default Setting: Disabled – Configuration Required |
|||
|
AMF provides the following support for rolling upgrade optimization:
This optimization helps in reduced session and call events per second (CEPS) loss during the upgrade procedure. The configurable rolling upgrade enhancements enable smooth rollout of the changes.
Command introduced:
Default Setting: Disabled – Configuration Required |
Behavior Changes
This section covers a brief description of behavior changes introduced in this release.
| Behavior Change | Description |
|---|---|
|
Generate Pod Logs in JSON Format |
Previous Behavior: AMF did not have functionality to generate pod logs in JSON format. However, this functionality was present in the CDL application. New Behavior: AMF can now generate pod logs in JSON format using the logging json-logging [ application | monitor-subscriber | transaction ] CLI command. Once this feature is activated, all AMF-related application pods begin generating logs in JSON for the selected log types. |
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.
Certificate Validation
AMF 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.
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 table below.
|
Operating System |
SHA512 checksum calculation command examples |
||
|---|---|---|---|
|
Microsoft Windows |
Open a command line window and type the following command:
|

|
Apple MAC |
Open a terminal window and type the following command:
|
||
|
Linux |
Open a terminal window and type the following command:
OR
|
||
|
|||
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.

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.
