Behavior Changes for this Release
The following behavior changes are visible in this release.
Handling Peer Delete Log during Reload
Previous Behavior: The application error log was captured even if the ETCD entry was deleted for a valid scenario.
Following is an example of error log where this log is marked as ERROR.
2024/03/08 06:22:38.700 smf-service-6 [ERROR] [MemoryCache.go:446] [infra.memory_cache.core] Reload cache, key C.GR.1.peergtpnodeinfo1.x.x.x.x deleted
New Behavior: The log level of this error log is changed to debug as this log is getting printed in the valid scenario.
SGW Peer Detection in Roaming Scenario
Previous Behavior: Roaming S-GW peers were showing as UNKNOWN_PEER in nodemgr logs and not tagged as "Roaming" in the SMF CCG software release 2023.03.m0.d8.0.i45 when seen with show peers all command.

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:
|
||
|
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.
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.
