What's New in this Release
New in Documentation
This version of Release Notes includes a new section titled What’s New in this Release comprising all new features, enhancements, and behavior changes applicable for the release.
This section will be available in all the 5G release notes and will supersede content in the Release Change Reference (RCR) document. Effective release 2024.02, the RCR document will be deprecated.
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 |
|---|---|
|
You can now customize RADIUS messages by including or excluding specific attributes to meet your server's requirements. This feature enhances your control over shared data between RADIUS clients and servers and optimizes message performance by filtering unnecessary attributes, thus reducing server load. |
|
|
L3 Routed Subscriber Sessions with Subscriber Redundancy Group |
This feature enhances routing and redundancy for subscriber sessions by allowing subscribers to connect through a routed (L3) access network. |
|
You can now reduce the route count by using a single summary route for both Internet Assigned Numbers Authority (IANA) and Internet Address Prefix Delegation (IAPD) from a single IP pool. This feature optimizes the use of IPv6 prefix ranges and offers flexibility in address allocation. By introducing a virtual address range within the IPAM data structure, you can reserve the first prefix for IANA and use subsequent prefixes for IAPD with the split-prefix-iana-first command. |
|
|
This feature enhances troubleshooting by providing detailed records of past session disconnections in cnBNGs. This feature is crucial for understanding why sessions have been disconnected in the past, allowing for effective problem resolution and network management. |
|
|
This feature ensures reliable IPv6 client IP allocation by allowing static IP assignments based on class parameters within a DHCPv6 profile. |
|
|
This feature enhances session accounting by allowing the use of a single AAA profile for both session and service accounting, reducing the need for multiple feature templates. This simplifies the configuration process when connecting to multiple RADIUS servers. Accounting Send-Stop Setup-Failure improves session management by sending an accounting stop record in case of session setup failures, ensuring that the RADIUS server clears stale session entries. |
|
|
We now support deploying the cnBNG Control Plane on a Red Hat OpenShift cluster. |
|
|
We have now introduced CP geo redundancy support for PPPoE sessions. |
|
|
We have now added Subscriber Redundancy Group (SRG) support for PPPoE sessions. |

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 cnBNG CP 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
cnBNG CP software images are signed via x509 certificates. View the .README file packaged with the software for information and instructions on how to validate the certificates..
