Release Notes for Cisco vEdge Devices, Cisco SD-WAN Release 20.9.x

Release Notes for Cisco vEdge Device, Cisco SD-WAN Release 20.9.x

Note

To achieve simplification and consistency, the Cisco SD-WAN solution has been rebranded as Cisco Catalyst SD-WAN. In addition, from Cisco IOS XE SD-WAN Release 17.12.1a and Cisco Catalyst SD-WAN Release 20.12.1, the following component changes are applicable: Cisco vManage to Cisco Catalyst SD-WAN Manager, Cisco vAnalytics to Cisco Catalyst SD-WAN Analytics, Cisco vBond to Cisco Catalyst SD-WAN Validator, Cisco vSmart to Cisco Catalyst SD-WAN Controller, and Cisco Controllers to Cisco Catalyst SD-WAN Control Components. See the latest Release Notes for a comprehensive list of all the component brand name changes. While we transition to the new names, some inconsistencies might be present in the documentation set because of a phased approach to the user interface updates of the software product.

These release notes accompany the Cisco SD-WAN Release 20.9.x, which provides Cisco Catalyst SD-WAN capabilities. They include release-specific information for Cisco Catalyst SD-WAN Controllers, Cisco Catalyst SD-WAN Validators, Cisco SD-WAN Manager as applicable to Cisco vEdge devices.

What's New for Cisco SD-WAN Release 20.9.x

This section applies to Cisco vEdge 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.

Table 1. Cisco SD-WAN Release 20.9.2
Feature	Description
Systems and Interfaces
Synchronized device lists in Cisco SD-WAN Manager	This feature synchronizes the device lists on the Configuration > Devices and Monitor > Devices pages. The Monitor > Devices page now displays the devices that are newly added or synced to Cisco SD-WAN Manager using the options available on the Configuration > Devices page.

Table 2. Cisco SD-WAN Release 20.9.1
Feature	Description
Cisco Catalyst SD-WAN Getting Started
Support for License Management Using a Proxy Server	If you configure Cisco SD-WAN Manager to use a proxy server for internet access, Cisco SD-WAN Manager uses the proxy server to connect to Cisco SSM or an on-premises SSM.
Support for Managing Licenses Using Cisco Smart Software Manager On-Prem	Cisco SD-WAN Manager supports management of device licenses, using a Cisco SSM On-Prem license server. This is useful for organizations that use Cisco SSM On-Prem to accommodate a strict security policy that does not permit devices to communicate with Cisco SSM over a direct internet connection.
Renew Device CSR	This feature allows you to reset the RSA private and public keys, and generate a CSR that uses a new key pair. In earlier releases, the generation of CSR used the existing key pair.
Systems and Interfaces
Hardened Passwords	This feature lets you configure Cisco SD-WAN Manager to enforce predefined medium-security or high-security password criteria.
Network Hierarchy and Resource Management	This feature enables you to create a network hierarchy in Cisco SD-WAN Manager to represent the geographical locations of your network. The network hierarchy and the associated resource IDs, including region IDs and site IDs, help you apply configuration settings to a device. In addition, the introduction of the resource manager in Cisco SD-WAN Manager automatically manages these resource IDs, thereby simplifying the overall user experience of Cisco SD-WAN. You can create a region only if you enable the Multi-Region Fabric option in Cisco SD-WAN Manager.
Co-Management: Improved Granular Configuration Task Permissions	To provide a user with the ability to self-manage specific configuration tasks, you can assign the user permissions to configure specific features while excluding others. This feature introduces numerous new permission options, enabling fine granularity in determining which configuration task permissions to provide to a user.
RBAC for Security Operations and Network Operations Default User Groups	This feature provides the following default user groups: network_operations user group for non-security policies security_operations user group for security policies RBAC for policies allows you to create users and user groups with the required read and write permissions for security and non-security policies. Users can perform configuration and monitoring actions only for the authorized policy type.
Flexible Tenant Placement on Multitenant Cisco SD-WAN Controller	With this feature, while onboarding a tenant to a multitenant deployment, you can choose the pair of multitenant Cisco SD-WAN Controller that serve the tenant. After onboarding a tenant, you can migrate the tenant to a different pair of multitenant Cisco SD-WAN Controller to allow for more tenant WAN edge devices than was forecast during onboarding.
Routing
Route Leaking between Inter-Service VPN	This feature allows you to leak routes between service VPNs on the same edge device.
Policies
Custom Applications	This feature enables you to define custom applications using Cisco Software-Defined Application Visibility and Control (SD-AVC) support. This feature is available only on Cisco vEdge devices.
Application-Aware Routing for Hub and Spoke	This feature allows you to configure AAR for traffic coming from tunnel to tunnel on Cisco Catalyst SD-WAN devices. Prior to Cisco SD-WAN Release 20.9.1, AAR policy is applied only for packets coming from service going to tunnel. With this feature, you can apply AAR policy for packets coming from tunnel to tunnel as per SLA requirements.
Lawful Intercept	This feature enhances the support for Lawful Intercept in Cisco Catalyst SD-WAN. Cisco Catalyst SD-WAN's Lawful Intercept feature enables Cisco SD-WAN Manager and Cisco SD-WAN Controller to provide the key information to LEA so they can decrypt the Cisco Catalyst SD-WAN IPsec traffic captured by the MSP.
Security
Global SIG Credentials Template	With this feature, create a single global SIG Credentials template for each SIG provider (Cisco Umbrella or Zscaler). When you attach a SIG template to a device template, Cisco SD-WAN Manager automatically attaches the applicable global SIG Credentials template to the device template.
Disable Weak SSH Encryption Algorithms	This feature allows you to disable weaker SSH algorithms that may not comply with certain data security standards.
Cisco Catalyst SD-WAN Monitor and Maintain
Access TAC Cases from Cisco SD-WAN Manager	This feature allows you to access Support Case Manager (SCM) wizard using Cisco SD-WAN Manager. You can create, view, or edit the support cases directly from Cisco vManage without having to go to a different Case Manager portal.
Analyze the Health of the Cisco SD-WAN Manager Cluster and Cluster Services Using the CLI	With this feature, you can analyze the health of the Cisco SD-WAN Manager cluster and the status of the cluster services using the request nms cluster diagnostics CLI command.
Additional Real Time Monitoring Support for AppQoE and Other Configuration Options	This feature adds support for real-time monitoring for AppQoE and other device configuration details. Real-time monitoring in Cisco SD-WAN Manager is similar to using show commands in the CLI of a device.
Compare Template Configuration Changes Using Audit Logs	This feature introduces a Config Diff option for audit logs of device templates and feature templates. The Config Diff option shows configuration changes made to the template, comparing the current configuration and previous configuration. The Config Diff option is available for audit logs to view the configuration changes when a template is not attached to a device.
Customizable Monitor Overview Dashboard in Cisco vManage	This feature adds customizability to the Monitor Overview dashboard. It gives you the flexibility to specify which dashlets to view and sort them based on your personal preferences.
Schedule the Software Upgrade Workflow	This feature introduces an option to schedule software upgrades for edge devices using Cisco SD-WAN Manager.
Software Upgrade Workflow Support for Additional Platforms	Added support for Cisco Enterprise NFV Infrastructure Software (NFVIS) and Cisco Catalyst Cellular Gateways.
High Availability
Configure Disaster Recovery Alerts	This feature provides support for configuring Cisco SD-WAN Manager alerts to generate an alarm and a syslog message for any disaster recovery workflow failure or event that occurs.

Software and Hardware Behavior Changes in Cisco SD-WAN Release 20.9.1


Behavior Change	Description
A link is added from the Cisco SD-WAN Manager menu to the Cisco Catalyst SD-WAN Portal. From the Cisco Catalyst SD-WAN menu, click SD-WAN Portal to access the Cisco Catalyst SD-WAN Portal for provisioning, monitoring, and maintaining Cisco Catalyst SD-WAN controllers using public cloud providers.	A note is added in the Cisco Catalyst SD-WAN Solution section.
Support is added for configuration of a device access policy having only a default action and with no policy sequences. You can now create a device access policy with only a default action and with no policy sequences for creation of a device configuration or a Cisco SD-WAN Manager configuration for both protocols, Secure Shell (SSH) and Simple Network Management Protocol (SNMP).	A note is added in the Configure Device Access Policy Using Cisco vManage section.
A list of valid characters is added. These characters must be used in the user ID, password, and the URL name or path when downloading an image from a remote server manually.	A note is added in the Upgrade the Software Image on a Device section.
Support is added to throttle the elephant flow (EF) traffic on vEdge2k devices.	Added a new topic Elephant Flow Throttling in Policy Guide. The following new commands are added: elephant-flow custom-eflow match elephant-flow show policy ef-stats
We recommend that the Cisco SD-WAN Manager cluster interface should not be the same as the transport interface. Beginning with Cisco vManage Release 20.9.1, this is enforced. If you attempt to configure this, Cisco SD-WAN Manager displays an error message.	A note is added in the Guidelines for a Cisco SD-WAN Manager Cluster section.
A new option Umbrella DNS Certificate is available in Cisco SD-WAN Manager to upload and push to appropriate devices Umbrella root certificates for Umbrella DNS security.	The new Umbrella DNS Certificate option is described in the Upload Umbrella Root Certificates section.
A new option Remote Server (preferred) is available in Cisco SD-WAN Manager to add multiple remote locations and use the remote locations as the source of the virtual image.	A note is added in the Upload the Cisco Security Virtual Image to Cisco SD-WAN Manager section.
Configure the DNS cache timeout timer tracker-dns-cache-timeout command on Cisco vManage in the system configuration mode. Cisco vEdge devices cache DNS resolved SIG endpoint IP addresses for the duration of this timeout. When the cache times out, Cisco vEdge devices refresh the cache through new DNS resolution queries. The default timeout is two hours.	The new configuration option in the Support for Layer 7 Health Check section.
The Cisco Catalyst SD-WAN Control Components software version must be the same or be higher that the WAN edge device software version. If the WAN edge device software version is higher than the Control Componets software version, policy download to the device fails.	A note is added in Cisco Catalyst SD-WAN Control Components Compatibility Matrix and Recommended Computing Resources.
