Instant Overview

An Instant AP cluster consists of slave Instant APs and a master Instant AP in the same 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., as they communicate with broadcast messages. A virtual controller is a combination of the whole cluster, as the slave Instant APs and Master Instant AP coordinate to provide a controllerless Instant solution. In an Instant deployment scenario, the first Instant AP that comes up becomes the master Instant AP. All other Instant APs joining the cluster after that Instant AP, become the slave Instant APs.

In an Instant deployment scenario, only the first Instant AP or the master Instant AP needs to be configured. The other Instant APs download configurations from the first Instant AP that is configured. The Instant solution constantly monitors the network to determine the Instant AP that must function as a master Instant AP at a given time. The master Instant AP may change as necessary from one Instant AP to another without impacting network performance.

Each Instant AP model has a minimum required software version. When a new Instant AP is added into an existing cluster, it can join the cluster only if the existing cluster is running at least the minimum required version of that Instant AP. If the existing cluster is running a version prior to the minimum required version of the new Instant AP, the new Instant AP will not come up and may reboot with the reason Image sync fail. To recover from this condition, upgrade the existing cluster to at least the minimum required version of the new Instant AP first, and add the new Instant AP. For more information about supported Instant AP platforms, refer to the Aruba Instant Release Notes.

 

Aruba recommends that networks with more than 128 Instant APs be designed as multiple, smaller virtual controller networks with Layer-3 mobility enabled between these networks.

Aruba Instant APs are available in the following variants:
