Assign Gateways to a Group

A group in HPE Aruba Networking Central is a primary configuration element that acts like a container. Groups are a subset of one or several devices that share common configuration settings. HPE Aruba Networking Central supports assigning devices to groups for the ease of configuration and maintenance. For example, you can create a common group for Branch Gateways that have similar configuration requirements.HPE Aruba Networking gateways are used in the tunnel mode topology of AOS-10 deployments. In the tunnel mode topology, APs forward user traffic to a gateway cluster through a secure tunnel.

The HPE Aruba Networking gateways running ArubaOS 10.3.1.0 and later versions can form a cluster automatically when they are assigned to an UI group. Therefore, when you assign devices to a group, you must consider the following feature limitations:

  • A cluster can be made up of different gateway platform models. For instance, a combination of HPE Aruba Networking 7210, 7220, 7240 series gateways are allowed in the same cluster.

  • Based on the hardware platform type, a single cluster can consist of up to 12 HPE Aruba Networking 7200 Series gateways. Similarly, if the group consists of Aruba 7000 Series gateways, only four devices can form a cluster.

  • You can combine 7200 Series and 7000 Series gateways in the same cluster with a maximum size of four devices with reduced AP client capacity on 7000 Series gateways.

  • The groups in HPE Aruba Networking Central are not device-specific, so you can provision gateways, Switches, and APs in a single group. However, based on your deployment topology, you can assign these devices to the same or different groups.

  • A device can be part of only one group at any given time.

To assign HPE Aruba Networking gateways to a group, perform the following procedure:
