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 |
|---|---|
|
This feature allows UPF to enable load and overload control mechanisms to handle the messages during overloaded or self-protection state. Commands Introduced:
Default Setting: Disabled—Configuration required to Enable |
|
|
Handling PFCP Messages Using Message Prioritization during an Overload Scenario |
This feature allows the UPF to use message prioritization to ensure uninterrupted receival of incoming PFCP messages during an overload scenario or self-protection mode. Message Prioritization allows the network operator to define the message priority using the configuration to throttle the PFCP messages in overload scenarios for a WPS session. Command Enhanced: session-priority-profile spp_name priority priority_value type { wps | emergency | ims } { throttle | precedence precedence_value } Default Setting: Disabled—Configuration required to Enable |
Behavior Changes
There are no behavior changes introduced 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.
The following screenshot is an example of a UPF release posted in the Software Download page.
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 following table.
|
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 |
|
NOTES: filename is the name of the file. extension is the file 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
UPF 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
StarOS Version Numbering System
The output of the show version command displays detailed information about the version of StarOS currently running on the ASR 5x00 or Cisco Virtualized Packet Core platform.
The Version Build Number for releases 21.1 and later include a major and emergency release number, for example, "21.1.1".
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.
Note |
The 5G UPF software is based on StarOS and implements the version numbering system described in this section. However, as a 5G network function (NF), it is posted to Cisco.com under the Cloud Native Product Numbering System as described in Cloud Native Product Version Numbering System. |
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.
