n If the preference role is set to switch-less, the AP bypasses switch discovery and immediately enters
Instant discovery (skip to step 3 on page 518).
n If a switch is discovered, but the AP deployment policy is applied to this AP, the AP connects to the switch
and downloads the AOS-W image. The switch rejects the AP termination and redirects the AP to the
Instant discovery process.
3. If the AP cannot locate any switches, it enters the Instant discovery process to locate an Instant VC, Activate,
OmniVista, or Central.
4. The AP attempts to discover a VC in an existing IAP cluster.
5. If a VC is discovered, the AP joins the existing IAP cluster and downloads the Instant image from the cluster.
6. After the image is downloaded, the AP reboots.
7. The configuration syncs, and the AP runs in switch-less mode.
Switch-less AP via Activate, OmniVista, or Central
If the AP cannot locate a virtual switch in an existing IAP cluster, the AP attempts to connect to Activate,
OmniVista, or Central to upgrade the AP to the Instant image and form a new IAPcluster.
In this deployment scenario, Activate, OmniVista, or Central must be accessible to the AP.
APs are upgraded to the Instant image via Activate, OmniVista, or Central through the following steps:
1. The AP boots up with the manufacturing image in unprovisioned mode.
2. The AP enters the switch discovery process using static/DHCP/ADP/DNS based switch discovery.
n If the preference role is set to switch-less, the AP bypasses switch discovery and immediately enters
Instant discovery (skip to step 3 on page 518).
n If a switch is discovered, but the AP deployment policy is applied to this AP, the AP connects to the switch
and downloads the AOS-W image. The switch rejects the AP termination and redirects the AP to the
Instant discovery process.
3. If the AP cannot locate any switches, it enters the Instant discovery process to locate an Instant VC, Activate,
OmniVista, or Central.
4. The AP attempts to discover a VC in an existing IAP cluster.
5. If the AP cannot locate a VC in an existing IAP cluster, the AP attempts to locate Activate, OmniVista, or
Central to upgrade the image and form a new IAP cluster.
APs running the manufacturing image cannot form an IAPcluster.
n If the AP locates Activate, it receives pre-configured provisioning rules to connect to OmniVista/Central
or convert into a campus AP (CAP) or remote AP (RAP).
APs that connect to Activate are automatically upgraded from the manufacturing image to the latest Instant/AOS-W
image. Refer to the latest Alcatel-Lucent Activate User Guide for more details on configuring provisioning rules.
n If the AP locates OmniVista, it can be upgraded to the Instant image. If an enforced image upgrade rule is
configured in OmniVista, the AP is upgraded to the Instant image configured for the enforced upgrade
rule. If no enforced upgrade rule is configured, the AP is upgraded to the latest Instant image in
OmniVista. After the AP is upgraded, it reboots in switch-less mode. Refer to the latest OmniVista 8.x User
Guide for details on AP image upgrade.
