Description

Network Hierarchy and Resource Management

Cisco IOS XE Catalyst SD-WAN Release 17.9.1a

Cisco vManage Release 20.9.1

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 Catalyst SD-WAN.

Note that you can create a region only if you enable the Multi-Region Fabric option in Cisco SD-WAN Manager.

Network Hierarchy and Resource Management (Phase II)

Cisco IOS XE Catalyst SD-WAN Release 17.10.1a

Cisco vManage Release 20.10.1

The following enhancements are introduced in the Network Hierarchy and Resource Management feature.

  • Creation of a system IP pool on the Configuration > Network Hierarchy page

  • Automatic assignment of site ID, system IP, and hostname to a device in the Quick Connect workflow

  • Display of detailed information on the Configuration > Network Hierarchy page, including site ID pool, region ID pool, and the list of devices associated with a site

Support for Software Defined Remote Access Pools

Cisco IOS XE Catalyst SD-WAN Release 17.11.1a

Cisco vManage Release 20.11.1

Remote access refers to enabling secure access to an organization's network from devices at remote locations. The resource pool manager manages the IPv4 and IPv6 private IP address pools for Cisco Catalyst SD-WAN remote access devices.

You can create a software defined remote access pool using the Configuration > Network Hierarchy page.

Support for Traffic Flow Collectors

Cisco IOS XE Catalyst SD-WAN Release 17.13.1a

Cisco Catalyst SD-WAN Manager Release 20.13.1

This feature enables you to configure traffic flow collectors such as the Cflowd server and security logging server. Cflowd monitors service side traffic flowing through devices in the overlay network and exports flow information to the collector. Enable security logging and configure servers for high-speed logging (HSL) and collecting external syslogs.

You can configure the traffic flow collectors by navigating to Configuration > Network Hierarchy > Collectors.

Information About Network Hierarchy and Resource Management

Overview of Network Hierarchy

You can create a network hierarchy in Cisco SD-WAN Manager to represent the geographical locations of your network. Your network hierarchy can contain three types of nodes—regions, areas, and sites. The resource IDs assigned to the nodes help you identify where to apply configuration settings later.

By default, there is one node called global in the network hierarchy.

The network hierarchy has a predetermined hierarchy with three types of nodes:

  • Region: It represents a region in a multiregion fabric-based Cisco Catalyst SD-WAN deployment. The Multi-Region Fabric feature provides the option to divide the architecture of the Cisco Catalyst SD-WAN overlay network into multiple regional networks that operate distinctly from one another, and a central core-region network for managing inter-regional traffic.

    You can create a region only if you enable the Multi-Region Fabric option in Cisco SD-WAN Manager. For complete information about the Multi-Region Fabric feature, see the Cisco Catalyst SD-WAN Multi-Region Fabric (also Hierarchical SD-WAN) Configuration Guide.

  • Group/Area: A group, also called an area, is a logical grouping of nodes in a network hierarchy. You can group sites, regions, other areas, or any combination of these into an area.

  • Site: A site is the lowest level of node or the leaf node in a network hierarchy. You cannot create a child node under a site. You can only associate devices to a site.

For complete information about creating and managing different nodes in a network hierarchy, see Manage a Network Hierarchy.

Overview of Resource Management

The resource manager in Cisco SD-WAN Manager manages the resource IDs, that is, region IDs and site IDs. It automatically generates a region ID for a region that you create on the Configuration > Network Hierarchy page. Similarly, it generates a site ID for a site if you do not specify it.

You can assign a site ID and a region ID to a device. For complete information about assigning resource IDs to devices, see Assign Resource IDs to Devices.

If you upgrade from an earlier version of Cisco SD-WAN Manager to Cisco vManage Release 20.9.1, the resource manager in Cisco SD-WAN Manager automatically creates sites based on the site IDs of the existing devices in your setup. Sites are named as SITE_<id>. Cisco SD-WAN Manager displays these sites under the global node on the Network Hierarchy page. It also associates the existing devices with their sites in the network hierarchy.

Benefits of Network Hierarchy and Resource Management

  • Automates the management of regions and sites.

  • Saves the manual effort in an upgrade scenario when Cisco SD-WAN Manager discovers all your existing sites and displays them in the network hierarchy.

  • Simplifies the onboarding and configuration of devices.

  • Monitors and collects information about traffic flow.

Supported Devices for Network Hierarchy and Resource Management

This feature is supported on Cisco IOS XE Catalyst SD-WAN devices and Cisco vEdge devices.

Restrictions for Network Hierarchy and Resource Management

  • You can delete a node only if it does not have any child node. For example, you can delete a site only if no devices are associated with it.

  • A site is the lowest level of a node or the leaf node in a network hierarchy. You cannot create a child node under a site.

  • You cannot create more than one region node between the global node and a site node.

  • You cannot create a region in a multitenant deployment.

  • The maximum combined number of regions and secondary regions is 63 (region ID numbers 1 through 63).
