Release Notes for Cisco IOS XE SD-WAN Release 16.12.x
 Note |
The documentation set for this product strives to use bias-free language. For purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on standards documentation, or language that is used by a referenced third-party product. |
These release notes accompany the Cisco IOS XE SD-WAN Release 16.12.x, which provides Cisco SD-WAN capabilities for Cisco IOS XE SD-WAN devices. They include release-specific information for Cisco vSmart Controllers, Cisco vBond Orchestrators, Cisco vManage, as applicable to Cisco IOS XE SD-WAN devices.

What's New for Cisco IOS XE SD-WAN Releases 16.12.1b, 16.12.1d, and 16.12.2r
This section applies to Cisco IOS XE SD-WAN devices.
Cisco is constantly enhancing the SD-WAN solution with every release and we try and keep the content in line with the latest enhancements. The following table lists new and modified features we documented in the Configuration, Command Reference, and Hardware Installation guides. For information on additional features and fixes that were committed to the SD-WAN solution, see the Resolved and Open Bugs section in the Release Notes.
|
Feature |
Description |
|---|---|
|
Getting Started |
|
|
API Cross-Site Request Forgery Prevention |
This feature adds protection against Cross-Site Request Forgery (CSRF) that occurs when using Cisco SD-WAN REST APIs. This protection is provided by including a CSRF token with API requests. You can put requests on an allowed list so that they do not require protection if needed. See Cross-Site Request Forgery Prevention. |
|
Systems and Interfaces |
|
|
IPv6 Support for NAT64 Devices |
This feature supports NAT64 to facilitate communication between IPv4 and IPv6 on Cisco IOS XE SD-WAN devices. See IPv6 Support for NAT64 Devices. |
|
Secure Shell Authentication Using RSA Keys |
This feature helps configure RSA keys by securing communication between a client and a Cisco SD-WAN server. See SSH Authentication using vManage on Cisco XE SD-WAN Devices. See Configure SSH Authentication. |
|
DHCP option support |
This feature allows DHCP server options, 43 and 191 to configure vendor-specific information in client-server exchanges. See Configure DHCP. |
|
Communication with an UCS-E Server |
This feature allows you to connect a UCS-E interface with a UCS-E server through the interface feature template. See Create a UCS-E Template. |
|
Bridging, Routing, Segmentation, and QoS |
|
|
QoS on Subinterface |
This feature enables Quality of Service (QoS) policies to be applied to individual subinterfaces. See QoS on Subinterface. |
|
Policies |
|
|
Packet Duplication for Noisy Channels |
This feature helps mitigate packet loss over noisy channels, thereby maintaining high application QoE for voice and video. See Configure and Monitor Packet Duplication. |
|
Control Traffic Flow Using Class of Service Values |
This feature lets you control the flow of traffic into and out of a Cisco device's interface based on the conditions defined in the quality of service (QoS) map. A priority field and a layer 2 class of service (CoS) were added for configuring the re-write rule. See Configure Localized Data Policy for IPv4 Using Cisco vManage. |
|
Integration with Cisco ACI |
The Cisco SD-WAN and Cisco ACI integration functionality now supports predefined SLA cloud beds. It also supports dynamically generated mappings from a data prefix-list and includes a VPN list to an SLA class that is provided by Cisco ACI. See Integration with Cisco ACI. |
|
Encryption of Lawful Intercept Messages |
This feature encrypts lawful intercept messages between a Cisco IOS XE SD-WAN device and a media device using static tunnel information. See Encryption of Lawful Intercept Messages. |
|
Security |
|
|
High-Speed Logging for Zone-Based Firewalls |
This feature allows a firewall to log records with minimum impact to packet processing. See Firewall High-Speed Logging. |
|
Self zone policy for Zone-Based Firewalls |
This feature can help define policies to impose rules on incoming and outgoing traffic. See Apply Policy to a Zone Pair in Use the Policy Configuration Wizard. |
|
Secure Communication Using Pairwise IPsec Keys |
This feature allows you to create and install private pairwise IPsec session keys for secure communication between an IPsec device and its peers. See IPSec Pairwise Keys Overview. |
|
Network Optimization and High Availability |
|
|
TCP Optimization |
This feature optimizes TCP data traffic by decreasing any round-trip latency and improving throughput. See TCP Optimization: Cisco XE SD-WAN Routers. |
|
Share VNF Devices Across Service Chains |
This feature lets you share Virtual Network Function (VNF) devices across service chains to improve resource utilisation and reduce resource fragmentation. See Share VNF Devices Across Service Chains. |
|
Monitor Service Chain Health |
This feature lets you configure periodic checks on the service chain data path and reports the overall status. To enable service chain health monitoring, NFVIS version 3.12.1 or later should be installed on all CSP devices in a cluster. See Monitor Service Chain Health. |
|
Manage PNF Devices in Service Chains |
This feature lets you add Physical Network Function (PNF) devices to a network, in addition to the Virtual Network function (VNF) devices. These PNF devices can be added to service chains and shared across service chains, service groups, and a cluster. Inclusion of PNF devices in the service chain can overcome the performance and scaling issues caused by using only VNF devices in a service chain. See Manage PNF Devices in Service Chains. |
|
Devices |
|
|
Cisco 1101 Series Integrated Services Routers |
Cisco SD-WAN capability can now be enabled on Cisco 1101 Series Integrated Services Routers. |
|
Commands |
|
|
Loopback interface support for WAN (IPsec) |
This feature allows you to configure a loopback transport interface on a Cisco IOS XE SD-WAN device for troubleshooting and diagnostic purposes. See the bind command. |
New and Enhanced Hardware Features
New Features
-
Support for UCS-E module—This feature adds a UCS-E template in Cisco vManage for configuring Cisco Unified Computing System (UCS) E-Series servers. For related information, see Getting Started Guide for Cisco UCS E-Series Servers and the Cisco UCS E-Series Network Compute Engine and Configuring Devices using vManage.
Note
Currently, backplane interfaces are not supported for UCS-E module. Only external connectivity is supported.
-
Support for Cisco IR1101 Integrated Services Router Rugged—Cisco SD-WAN capability can now be enabled onCisco IR1101 Integrated Services Router Rugged. The following notes apply to this support:
-
Controller devices (Cisco vBond orchestrators, Cisco vManage NMSs, and Cisco vSmart controllers) must run Cisco SD-WAN Release 19.2 or later.
-
The default topology is full mesh, but the hub and spoke topology is often used for IoT applications.
-
Cisco SD-WAN support on the Cisco IR1101 Integrated Services Router Rugged requires Cisco IOS-XE Release 16.12.
-
The Cisco IR1101 Integrated Services Router Rugged has four fixed switch-ports. Make sure to select the correct template.
-
The CLI template is not currently supported.
-
Starting from Cisco IOS-XE Release 16.12.1, Cisco IR1101 Integrated Services Router Rugged has dual LTE support with LTE extension module.
-
We recommend using up to 50 BFD sessions for scaling.
-
Important Notes, Known Behavior, and Workaround
-
Cisco IOS XE SD-WAN devices with the SFP-10G-SR module do not support online insertion and removal (OIR) of this module.
-
When you complete a Cisco SD-WAN software downgrade procedure on a device, the device goes into the configuration mode that it was in when you last upgraded the Cisco SD-WAN software on the device. If the device is in a different configuration mode when you start the downgrade than it was when you last upgraded, the device and Cisco vManage show different configuration modes after the downgrade completes. To put the configuration modes back in sync, reattach the device to a device template. After you reattach the device, both the device and Cisco vManage show that the device is in the vManage configuration mode.

For the ISR 1000 series routers, ROMmon version 16.8(1r) is not compatible with 16.10 releases and ROMmon version 16.9(1r) is not compatible with 16.9 releases. If an ISR 1000 series router is upgraded to a 16.10 release without auto-upgrade support, it is required that ROMmon be upgraded to 16.9(1r) or later by the user. |
