Connecting HPE Aruba Networking Gateways to HPE Aruba Networking Central

The HPE Aruba Networking gateways have the ability to automatically provision themselves and connect to HPE Aruba Networking Central once they are powered on. The gateways also support multiple active uplinks for ZTP Zero Touch Provisioning. ZTP is a device provisioning mechanism that allows automatic and quick provisioning of devices with a minimal or at times no manual intervention. (also referred to as automatic provisioning). The supported ZTP ports for different hardware platforms are listed in the following table. All these ZTP ports are assigned to VLAN Virtual 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. 4094.

To automatically provision the gateways:

1. Connect your SD-Branch gateway to the provisioning network.
2. Wait for the device to obtain an IP address through DHCP Dynamic 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. .

   Gateways support multiple uplink ports. The first port to receive the DHCP IP connects to the HPE GreenLake platform and completes the provisioning procedure:

• If the device has factory default configuration, it receives an IP address through DHCP, connects to HPE GreenLake platform, and downloads the provisioning parameters. When a device identifies HPE Aruba Networking Central as its management entity, it automatically connects to HPE Aruba Networking Central.
• If the device is running a software version that does not have the SD-Branch image, the devices are automatically upgraded to a supported SD-Branch software version.

  72xx gateways with the AOS 8.3.0.9 factory default image use only port 0/0/1 (the last copper port) for ZTP. When the factory default gateways connect to HPE GreenLake platform through ZTP for the first time, HPE GreenLake platform recommends a base AOS-10 image, which the gateways will download. In the AOS-10 image, port 0/0/1 is used as a debug port, and DHCP requests will not be sent out of port 0/0/1 for subsequent ZTP requests. Hence, ZTP workflow for 72xx gateways with the AOS 8.3.0.9 factory default image will not work. You must manually upgrade the HPE Aruba Networking 72xx gateways to the AOS-10 image or use other methods like full-setup and static-activate to provision the gateways.

   Table 2 describes the LED behavior.

Table 2: LED Indicators

LED Indicator	LCD Text	Description
Solid Amber	Getting DHCP IP	Indicates that the uplink connection is UP, but DHCP IP is yet to be retrieved.
Blinking Amber	Activate Wait	Indicates that the device was able to reach the DHCP server and the connection HPE GreenLake platform to the is yet to be established.
Solid Green	Activate OK	Indicates that the device was able to retrieve provisioning parameters from the HPE GreenLake platform.
Alternating Solid Green and Amber	Activate Error	Indicates that the device was not able to retrieve provisioning parameters.

After successfully connecting to HPE Aruba Networking Central, the gateways download the configuration from HPE Aruba Networking Central.
