— When you add devices to a configuration group using rules, you can choose Match All or Match Any.

— You can use Starts With and Ends With operator conditions when you add devices to a configuration group using rules.

— In addition, the button formerly called Add New Tag is now Create New Tag.

VFR (Virtual Fragmentation Reassembly) and Underlay Fragmentation

The VFR mechanism reassembles fragmented packets in Cisco Catalyst SD-WAN networks. The packets are fragmented for better transportion and are fragmented while they are travelling through a VFR enabled Cisco IOS XE Catalyst SD-WAN device.

Underlay fragmentation fragments packets in the underlying layer of a network. Underlay fragmentation is introduced to easily transport larger packets that exceed the (MTU).

Enhanced Cisco Catalyst SD-WAN Manager Dashboard for Multitenancy

This feature is enhanced to support consistent user experience in tenant and service providers dashboard.

The Cisco Catalyst SD-WAN Manager dashboard provides visibility into the available resources on shared devices.

RADIUS/TACAS Support for Multitenancy

This feature enables support for Remote Authentication Dial-In User Service (RADIUS) and Terminal Access Controller Access Control System (TACACS) authentication in a multitenant deployment on WAN edge devices.

Enhanced Multitenant Tier Definition to include NAT Limits

This feature is enhanced to support NAT to enforce per tenant maximum limit on the translations.

From this release Tier is called Resource Profile in Cisco SD-WAN Manager.

Cisco Catalyst SD-WAN Routing Configuration Guide

Transport Gateways

A transport gateway operates as the hub in a hub-and-spoke routing topology. It offers the advantage of achieving this topology without requiring complex routing policy configuration. The following are some uses of a transport gateway:

  • Providing connectivity to routers in disjoint underlay networks

  • Serving as a gateway (hub) for all traffic in one discrete network to reach another discrete network, such as directing all local network traffic to a cloud gateway

Hub-and-Spoke Configuration

Hub-and-spoke configuration simplifies the process of configuring a hub-and-spoke topology, making complex centralized control policy unnecessary. Instead, the configuration requires only a few simple configurations: a single command each on (a) the Cisco SD-WAN Controllers serving a network, (b) a router that serves as a hub, and (c) the routers that operate as spokes.

Symmetric Routing

You can use affinity groups, affinity group preference, and translation of RIB metrics to ensure symmetric routing of traffic flows across devices in a network. Symmetric routing accommodates various network topologies, including Multi-Region Fabric.

To support symmetric routing beyond the overlay network, transport gateways can translate RIB metrics to control plane protocols such as BGP and OSPF. This extends the path preference configuration to routers outside of the overlay network, such as routers in a data center LAN.

Cisco Catalyst SD-WAN Policies

WAN Insight Policy Automation

With this feature, you can apply the recommendations that are available on vAnalytics to Cisco SD-WAN Manager AAR policy and view the applied recommendations on Cisco SD-WAN Manager.

Flow Telemetry Enhancement When Using Loopbacks as TLOCs.

When you configure a loopback interface as an ingress or egress transport interface, this feature enables you to collect loopback interface reports in FNF records and is supported for IPv4 and IPv6.

A show command is enhanced on the device to display the binding relationship between the loopback and physical interfaces.

Lawful Intercept 2.0 Enhancements

This feature lets you configure intercepts in the Cisco Catalyst SD-WAN multitenancy mode, and also provides support for Cisco Catalyst SD-WAN Manager clusters.

Enhancements to Flexible NetFlow for vAnalytics

This feature introduces logging enhancements to Cisco Flexible NetFlow for Cisco SD-WAN Analytics.

The output of the show flow record command has been enhanced for IPv4 and IPv6 flow records.

Enhanced Application-Aware Routing

Without enhanced application-aware routing enabled, Cisco IOS XE Catalyst SD-WAN device require several minutes to switch traffic from one network path to another to meet SLA requirements when the loss, latency, and jitter exceed specific threshold values.

Enabling enhanced application-aware routing speeds the detection of tunnel performance issues. This enables Cisco IOS XE Catalyst SD-WAN devices to redirect traffic away from tunnels that do not meet SLA requirements.

Cisco Catalyst SD-WAN Security

Snort Engine Version Upgrade

This feature adds support for Snort engine version 3, which is an upgrade from version 2.

IPv6 GRE or IPsec Tunnels Between Cisco Catalyst SD-WAN and Third-Party Devices

This feature allows you to configure an IPv6 GRE or IPSEC tunnel from a Cisco IOS XE Catalyst SD-WAN device device to a third-party device over a service VPN.

Enabling MACsec using Cisco SD-WAN Manager

This feature adds support for enabling MACsec using Cisco SD-WAN Manager for Cisco Catalyst SD-WAN devices on the service side.

With MACsec enabled using Cisco SD-WAN Manager, communication between devices in the service VPN is protected, thus enhancing security for the service VPN.

OMP Prefixes for IP-SGT Binding

The OMP routes are typically present in the IOS RIB. The OMP routes aren't present in the IOS FIB containing entries that map destination IP addresses to next-hop IP addresses. The IOS FIB operates independently of the control plane, receiving the forwarding instructions from a centralized Cisco SD-WAN Controller instead of consuming the OMP routes from the IOS RIB. Starting from Cisco IOS XE Catalyst SD-WAN Release 17.12.1a, the OMP prefixes get added to the IOS FIB which improves IP-SGT binding.

Cisco Catalyst SD-WAN Cloud OnRamp

AWS Cloud WAN Integration

AWS Cloud WAN is a managed wide-area network (WAN) service. This feature enables you to easily connect and route remote sites, regions and cloud applications over the AWS global network. You can build and operate the wide-area networks using simple network policies and get a complete view of the global network.

Added an Azure Instance Type

For the Microsoft Azure West Central US and Australia East regions, added the Standard_D16_v5 Azure instance type, which includes 16 CPU cores and 64 GB of memory. You can deploy this type of instance for SKU scale values of 20, 40, 60, and 80.

Cisco Catalyst 8000V Edge Software Support

You can deploy a Cisco Catalyst 8000v Edge Software as the Interconnect Gateway in the Equinix fabric and connect an Cisco Catalyst SD-WAN branch location to the Interconnect Gateway.

Addition of VPC and VNet Tags to SDCI Connections

You can add or modify additional properties of Virtual Private Cloud (VPC) and Virtual Networks (VNets) tags that are associated with a connection.

Audit Management in Equinix

You can identify the gaps or disconnects between Cisco SD-WAN Manager intent and what is realized in the cloud. The audit management helps in understanding if the interconnect cloud and provider states are in sync with the Cisco SD-WAN Manager state.

Cisco Catalyst SD-WAN Policy Groups

Policy Groups

This feature provides a simple, reusable, and structured approach for configuring policies in Cisco Catalyst SD-WAN. You can create a policy group, that is, a logical grouping of policies that is applied to one or more sites or a single device at the site in the network. To deploy the policy group to devices, the devices must be managed by a configuration group in Cisco Catalyst SD-WAN. You can configure policies based on features that are required, recommended, or uniquely used, and then combine them to complete a policy configuration.

Security Policy Using Policy Groups

This feature provides a simple, reusable, and structured approach for configuring security policies in Cisco Catalyst SD-WAN. You can create a security policy, that is, a logical grouping of policies that is applied to one or more sites or a single device at the site in the network. To deploy the policy group to devices, the devices must be managed by a configuration group in Cisco Catalyst SD-WAN. You can configure policies based on features that are required, recommended, or uniquely used, and then combine them to complete a policy configuration.

Topology

This feature allows you to provision a Mesh or a Hub and Spoke topology policy which is applied to Cisco Catalyst SD-WAN Controllers. This allows exchange of data traffic between two or more Cisco IOS XE Catalyst SD-WAN devices.

New Features

  • Support for Cisco SM-X-1T3/E3 Module: Cisco SD-WAN Manager CLI device templates now supports Cisco SM-X-1T3/E3 module.

  • Support for Cisco Managed Cellular Activation (eSIM): The Managed Cellular Activation solution provides a programmable subscriber identity module (SIM), called an eSIM, a physical SIM card that you can configure with a cellular service plan of your choice. Managed Cellular Activation is available for the 5G Sub-6 GHz Pluggable Interface Module (PIM), model P-5GS6-GL, and for the Cisco Catalyst Wireless Gateway 113-4GW6.

    The solution also provides a "bootstrap" cellular plan with limited data for connecting your device to the internet on Day 0. You need to set up your cellular plan details in Cisco SD-WAN Manager before you power on and onboard the device. This way, you can avoid using up the data provided with the device before your onboarding is completed.

    For information about configuring Cisco SD-WAN Manager with the details of your cellular plan in preparation for onboarding the device, see the Cisco Managed Cellular Activation Configuration Guide.


    Note


    In this context, eSIM refers to a removable SIM pre-installed by Cisco. In other contexts, eSIM can refer to a non-removable SIM embedded in a cellular-enabled device.
