Assign Gateways to a Group

A group in Classic 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. Classic 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 AOS 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 Classic 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:
