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

Overload Optimization for GTPC Messages using Message Priority Negotiation

During WPS sessions, cnSGWc ensures smooth communication by defining the message priority for incoming messages and negotiating the message priority value for outgoing messages.

This feature allows the network operator to exempt the incoming WPS session messages by configuring the message priority under the overload exclude profile.

This feature also compares the message priority value of the incoming GTPC messages with the configured value and sets the lowest value for that session.

Commands Introduced: message-priority { any | s5e | s11 | sxa } upto message_priority

Default Setting: Disabled—Configuration required to Enable

Handling the Incoming Sx Messages at Self-overload State

The load and overload control capability of cnSGWc is enhanced to handle the incoming Sx message during the self-overload state.

This feature allows the cnSGWc to throttle the incoming DLDR session report request messages in the self-protection mode.

Behavior Changes

There are no behavior changes in this software 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 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.

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.

Table 1. 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 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

The software images are signed via x509 certificates. For information and instructions on how to validate the certificates, refer to the .README file packaged with the software.

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.
