Cisco DNA Center 2.3.4.x Release
There are some other enhancements with the release of Cisco DNA Center 2.3.4.x

  • NBAR: A protocol pack auto update feature can be enabled when configuring NBAR Cloud Connector.

  • Wireless Coverage Optimizer: You can use an optimizer tool if your wireless coverage isn't up to SLA standards. This tool computes a configuration where the wireless coverage is maximized based on the maximum number of APs that you are prepared to move and add that you enter.

  • Wireless Map: The GUI has undergone a few minor improvements to make it more reliable and consistent. For instance, when an element (such as a sensor, wall, or other feature) is removed from a wireless map, the element is only removed from the map. It is still present in Cisco DNA Center. To more accurately describe this action, the GUI terminology from Delete to Remove was changed.

  • Secure Tunnel: At a branch location, you can build an automatic, secure IPsec tunnel to a new edge device. This offers Cloud Security (Umbrella and Zscaler) and Enterprise connections high-speed, secure IPsec WAN connectivity.

  • RMA Support: Now Hardware stacking for Cisco switches through DNA Center. You can swap out full stack switches using Cisco DNA Center.

  • Security Group ACLs: During the access contract creation process, select the Modeled Access Contract option if you want Cisco DNA Center to generate the appropriate commands for the underlying Security Group ACLs (SGACLs). The access contract is built using a model that enables creation and editing without requiring knowledge of the underlying command line syntax when this option is enabled. If you want to directly enter the SGACL command lines and store the access contract as text, you can disable this option.

  • MRE Workflow: Troubleshoot Wireless APs Using the MRE Workflow

  • Cisco SD-Access: For your workplace, Cisco SD-Access offers a zero-trust security solution. Secure access is offered to all users and devices across your network by the Cisco SD-Access zero-trust security solution. Using endpoint visibility, trust monitoring, and network segmentation, the solution enables you to automate network access policies. Your journey toward a zero-trust workplace is outlined in the SD-Access Zero-Trust Overview dashboard.

  • Cisco SD-Access with WLC 9800: With Cisco Catalyst 9800 Series Wireless Controllers, remote LAN (RLAN) configuration is supported by Cisco DNA Center for fabric sites. On APs, RLAN ports can be set up for fabric sites. The wired clients are authenticated by Cisco Wireless Controller before being permitted to connect to the network.

  • Virtual network (VN) policy: You can now make a virtual network (VN) policy that permits Layer 3 VN to VN route leaks without the use of a peer device. Through DNA Center automation, use a VN policy to give endpoints (hosts or users) access to shared services like DHCP, DNS, Internet access, and so forth. A Provider VN is connected by the shared services. The shared service endpoints are housed in a Subscriber VN. Without allowing communication between the Subscriber VNs in the fabric, a VN policy establishes communication between the Provider VN and a Subscriber VN.
There are other updates as well as we covered the major ones here. You can check this on the below release notes.
