Aruba Central offers the following options to configure Gateways for SD-WANSoftware-Defined Wide Area Network. SD-WAN is an application for applying SDN technology to WAN connections that connect enterprise networks across disparate geographical locations. deployments:
- Groups—You can create a logical subset of devices as groups. If you have devices that must share common configuration settings, ensure that you assign these devices to the same group. Any new device joining a group inherits the configuration that is already applied to the devices in a group. Similarly, you can also maintain separate groups for Branch Gateways and VPNCs by assigning a group role for the devices. For more information, see Assigning Gateways to a Group.
- Device-specific configuration—If you have a considerably lesser number of devices that do not have the same configuration requirements, you can apply configuration changes at the device level. In some cases, although the devices are assigned to a group, you may want to have a slightly different configuration to one specific device in a group. In such cases, you can modify the device configuration and apply changes at the device level. Aruba Central marks the discrepancies in the group and device configuration as overrides on the Configuration Audit page.
- Bulk Configuration—Aruba Central supports several bulk configuration options for Aruba Gateways:
- Bulk Configuration Upload—Allows you to download a list of Aruba Gateways from Aruba Central in the CSVComma-Separated Values. A file format that stores tabular data in the plain text format separated by commas. file format. You can add the configuration parameters for hostname, system IP address, VLANVirtual Local Area Network. In computer networking, a single Layer 2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them through one or more routers; such a domain is referred to as a Virtual Local Area Network, Virtual LAN, or VLAN., and Ports, and then upload the CSV file to Aruba Central. For more information, see Uploading Bulk Configuration Template.
- Gateway Pools—Allows you to create a common pool of IP addresses and enables automatic assignment of IP addresses to Aruba Gateways. For more information, see Configuring Gateway Pools for Aruba Gateways.
- DHCPDynamic Host Configuration Protocol. A network protocol that enables a server to automatically assign an IP address to an IP-enabled device from a defined range of numbers configured for a given network. Pools—Allows you to configure a DHCP pool, using which Aruba Central automatically assigns a subnetSubnet is the logical division of an IP network. to each Aruba Gateway for a given VLAN. For more information, see Configuring DHCP Address Pools on Aruba Gateways.
- APIs—Allows you to configure and monitor devices using NB APIsApplication Programming Interface. Refers to a set of functions, procedures, protocols, and tools that enable users to build application software..
Different Modes of Configuring Gateways and Gateway Groups
Aruba Central supports the following methods to configure Gateway groups and Gateways.
- Aruba Gateways for deploying the SD-WANWide Area Network. WAN is a telecommunications network or computer network that extends over a large geographical distance. solution. The provides a wizard-based workflow for provisioning Gateways. The wizard allows you to configure Gateways at your own pace, pause, and resume when required. However, the Guided Setup will not be available after you complete the provisioning workflow for a Gateway group or a Gateway.
For more information on configuring Gateways using the Guided Setup, see the following topics:
—You can use the to quickly configure basic and essential parameters on
- Configuring an SD-Branch Network Using the Basic Setup.
Figure 1 Basic Mode
—Allows you to configure your Gateways in a non-linear fashion. This mode allows you to make configuration changes after you provision your gateways for the first time using a Guided setup. For more information, see
