Discover and Manage Access Points
158
ProSAFE Wireless Controller WC9500
After the access points are added to the Managed AP List, the wireless controller
upgrades the firmware of the access points to the latest firmware that is loaded on the
wireless controller, and the access points become managed access points. Depending
on the number of access points that you add to the Managed AP List, this process might
take several minutes.
By default, the access point upgrade process uses multicast. If you need to configure a
specific multicast IP address range for the upgrade process or disable multicast, see
Configure Multicast Firmware Upgrade for Access Points on page 265.
If one or more access points do not transition to the Connected state (see the Status
column in the Managed
AP List), see Resolve Problems with Access Points
on page 342.
For information about how to manage the Managed AP List, see Manage the Managed
AP List on page 163.
Discover Access Points Installed and Working in
Standalone Mode in Different Layer 3 Networks
Access points that are installed and working in standalone mode in different Layer 3 networks
are access points that do not function in the same subnet as the wireless controller but in
different IP ranges and that are connected to the wireless controller through a router.
Note: Make sure that DHCP option 43 (vendor-specific information) is
enabled on an external DHCP server. For more information, see
Layer 3 Discovery Guidelines on page 153.
In a large wireless network you might need to run the Discovery Wizard several times.
 To discover access points in different Layer 3 networks:
1. Open a web browser. In the browser’
s address field, type the wireless controller’s IP
address.
