Alcatel-Lucent AOS-W 6.5.3.x - Page 519

All firmware must be uploaded to OmniVista before the APconnects and downloads the Instant image. Refer to the
latest OmniVista 8.x Alcatel-Lucent Instant Deployment Guide for details on firmware upload.
n If the AP locates Central, it can be upgraded to the Instant image through the Maintenance >
Firmware page in the Central WebUI. After the AP is upgraded, it reboots in switch-less mode. Refer to
the latest Aruba Central User Guide for more details on AP image upgrade.
Central syncs with Alcatel-Lucent Activate to retrieve the latest Instant image.
After the AP is upgraded to switch-less mode, it forms a new IAP cluster and converts into the master. Other
un-deployed APs can join the cluster and upgrade to the Instant image.
Switch-less AP via Manual IAP Conversion
If the AP cannot be upgraded into an IAP through a virtual switch, Activate, OmniVista, or Central, users can
connect to a special provisioning SSID broadcasted by the unprovisioned AP to manually convert the AP to an
IAP through the WebUI. See Switch-less AP in an Instant Network on page 517 and Switch-less AP via Activate,
OmniVista, or Central on page 518 for details on upgrading an AP to the Instant image using a VC, Activate,
OmniVista, or Central.
To manually convert an AP to an IAP in the WebUI:
1. Login to your virtual switch.
2. Connect to the following provisioning SSID broadcasted by the unprovisioned AP:
SetMeUp-xx:xx:xx
3. Open a web browser. You will automatically be redirected to a special provisioning page in the WebUI to
convert the AP.
4. Under Access Point Setup, select Image File or Image URL to upload the Instant image.
n If you select Image File, click Browse to locate and select an Instant image file from your local file
explorer.
n If you select Image URL, enter the web address of the Instant image under URL.
5. Click Save.
After the AP is upgraded, it reboots in switch-less mode.
AP Deployments in Hybrid Switch-Instant Networks
Users can deploy APs into hybrid networks, which contain both switch-based and switch-less APs. APs in hybrid
networks are upgraded to the AOS-W or Instant image using the same methods as APs in pure switch or Instant
networks. However, the following items must be in place before deploying APs in a hybrid network:
n Switch-based APs and switch-less APs must run on different subnets (for example, a switch-based AP subnet
and a separate switch-less AP subnet).
n Different discovery methods should be used for switch-based APs and switch-less APs, as the switch
discovery process and Instant OmniVista discovery process share the same DHCP/DNS discovery methods.
For example, switch-based APs can use a DHCP server to discover a switch, while switch-less APs can use a
DNS server on OmniVista.
n If the same discovery method must be used for both switch-based APs and switch-less APs, Alcatel-Lucent
recommends that you use DHCP-based discovery. DHCP servers can respond to DHCP requests based on
the AP’s subnet and vendor ID. DNS servers do not have a subnet limit, which can cause the APs that share
a DNS server to be upgraded on the wrong AP subnet.
