ZTP with Aruba Central

Aruba Central does not require any options to be configured in the DHCP Dynamic Host Configuration Protocol. A network management protocol used for automatically assigning IP addresses and other communication parameters to devices connected to the network. server, but requires a DHCP Dynamic Host Configuration Protocol. A network management protocol used for automatically assigning IP addresses and other communication parameters to devices connected to the network. server in the network to provide IP address, default gateway, DNS Domain Name System. Hierarchical and distributed naming system for computers, services, and other resources in the Internet or other Internet Protocol (IP) networks.

Users with access to Aruba Central cloud portal must provision their switches and assign licenses accordingly. Once complete, Aruba Central will automatically program the Activate portal with the required switch details and the group to which the switch must check-in.

The following diagram illustrates the working of Aruba Central ZTP Zero Touch Provisioning. A method of setting up devices that automatically configures the device using a switch feature.:

The workflow is as follows:

1. The switches being provisioned in branches boot and connect to the Activate on the cloud.
2. Based on administrator’s provisioning (such as folder, rule), the device is placed in the appropriate folder before being redirected to the Aruba Central.
3. The switches check-in with Central and the server pushes the configuration to the switches based on the group, switch model, and branch location.

For more information on Aruba Central configuration, refer to the Aruba Central Configuration Guide.

• REST Representational State Transfer. The architecture for web services APIs.
