Cisco just released the latest version of SD-WAN 20.8.1 / SD-WAN IOS-XE 17.8.1. 

Here is a Summary of Some of the New Features 

Configuration Groups and Feature Profiles 

You can create a configuration group, that is, a logical grouping of devices that share a common purpose within your WAN. You can also create profiles based on features that are required, recommended, or uniquely used, and then combine the profiles to complete a device configuration. 

User-Defined Device Tagging 

This feature helps you add tags to devices. You can use the tags for grouping, describing, finding, or managing devices. 

Cisco ThousandEyes Support for Cisco Catalyst 8500 Series Edge Platforms and Cisco ASR 1000 Series Aggregation Services Routers 

You can deploy Cisco ThousandEyes Enterprise agent natively as a container application on supported Cisco IOS XE SD-WAN devices to integrate Cisco SD-WAN with Cisco ThousandEyes. You can install and activate the Cisco ThousandEyes Enterprise agent through Cisco vManage. By integrating Cisco SD-WAN with Cisco ThousandEyes, you can gain granular insights into network and application performance with full hop-by-hop path analysis across the Internet, and isolate fault domains for expedited troubleshooting and resolution. You can deploy Cisco ThousandEyes Enterprise agent natively as a container application on Cisco Catalyst 8500 Series Edge Platforms and Cisco ASR 1000 Series Aggregation Services Routers. You can install and activate the Cisco ThousandEyes Enterprise agent through Cisco vManage. 

Layer 7 Health Check for Manual Tunnels 

You can create and attach trackers to manually created GRE or IPSec tunnels to a SIG endpoint. Trackers help failover traffic when a SIG tunnel is down. 

SIG Integration Improvements 

Source-Only Load Sharing: When you configure two or more active tunnels to a Secure Internet Gateway (SIG), different traffic flows from the same source IP address, with different destination public IP addresses, may be mapped to use different tunnels. With this feature, you can configure all traffic flows from a particular source IP address, irrespective of the destination IP address, to be routed to the SIG through only one of the active tunnels. 

IPSec Tunnel Creation Improvements in an Active-Active Setup: This feature ensures that when you provision an IPSec tunnel, the control and data traffic are sent through the same the physical interface toward the SIG endpoint. Pinning the control and data packets to the same physical interface removes a limitation that exists in previous releases.
