Behavior Changes
This section covers a brief description of behavior changes introduced in this release.
| Behavior Change | Description |
|---|---|
|
Handling FHT Terminate Sub Action in CCA-I |
Previous Behavior: SMF terminates the session without sending the Gy CCR-T whenever the Gy CCR-I has failed with FHT action Terminate and sub action WITH_TERM_REQUEST. New Behavior: SMF terminates the session and sends the Gy CCR-T whenever the Gy CCR-I fails with FHT action Terminate and sub action WITH_TERM_REQUEST. |
|
Validity Time and Volume/Time Quota Threshold Usage for FUI URR |
Previous Behavior: SMF used to initially trigger CCR-U whenever exhaustion of volume or time quota is reported by UPF for any FUI MSCC. SMF reports the usage in Gy-CCRU to OCS without RSU and subsequently terminates the PDU session. When SMF receives time quota threshold usage from UPF for FUI URR, it neither terminates the PDU session nor request any further quota. New Behavior: For FHT with Continue action, SMF terminates the PDU session immediately after receiving quota exhaustion for any FUI URR and reports the final usage to OCS through Gy-CCRT if CLI is configured to terminate the session or had received command level FUI. SMF sends Gy-CCRT to OCS with Termination Cause "DIAMETER-ADMINISTRATIVE" and MSCC Reporting reason as "FINAL". If the usage report is received due to volume/time threshold or validity time, SMF reports the usage report only through Gy-CCR-U and continues to request for further quota. When both time quota and validity time are received and the time quota exceeds validity time or when validity time alone is received without time quota, then SMF sends Gy-CCRU with MSCC reporting reason as "VALIDITY-TIME" and requests further quota. |
|
Quota Allocation for Online FUI and non-FUI URRs |
Previous Behavior: SMF used to allocate the maximum quota only to non-FUI online URRs for a FHT with Continue action and None/Unknown sub-action. SMF sends Gy-offline-flag to UPF setting it to True. New Behavior: SMF allocates the maximum quota to both FUI and non-FUI online URRs after FHT with Continue action and None/Unknown sub-action. SMF subsequently sends Gy-offline-flag to UPF with the flag set to True. |

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 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 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:

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
SMF 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.

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.
