Discovery and registration overview
When the Altitude AP is powered on, it automatically begins a discovery process to determine its own
IP address and the IP address of the Summit WM Controller. When the discovery process is successful,
the Altitude AP registers with the Summit WM Controller.
WARNING!
Only use power supplies that are recommended by Extreme Networks.
Altitude AP discovery
Altitude APs discover the IP address of a Summit WM Controller using a sequence of mechanisms that
allow for the possible services available on the enterprise network. The discovery process is successful
when the Altitude AP successfully locates a Summit WM Controller to which it can register.
You must ensure that the appropriate services on your enterprise network are prepared to support the
discovery process. The following five steps summarize the discovery process:
Step 1 - Use the IP address of the last successful connection to a Summit WM Controller.
Once a Altitude AP has successfully registered with a Summit WM Controller, it recalls that
controller's IP address, and uses that address on subsequent reboots. The Altitude AP bypasses
discovery and goes straight to registration.
If this discovery method fails, it cycles through the remaining steps until successful.
Step 2 - Use the predefined static IP addresses for the Summit WM Controllers on the network (if
configured).
You can specify a list of static IP addresses of the Summit WM Controllers on your network. On the
Static Configuration tab, add the addresses to the Wireless Controller Search List.
CAUTION
Altitude APs configured with a static Altitude Controller Search List can only connect to Summit WM Controllers
in the list. Improperly configured Altitude APs cannot connect to a non-existent Summit WM Controller address,
and therefore cannot receive a corrected configuration.
Step 3 - Use Dynamic Host Configuration Protocol (DHCP) Option 78 to locate a Service Location
Protocol (SLP) Directory Agent (DA), followed by a unicast SLP request to the Directory Agent.
To use the DHCP and unicast SLP discovery method, you must ensure that the DHCP server on
your network supports Option 78 (DHCP for SLP RFC2610). The Altitude APs use this method to
discover the Summit WM Controller.
This solution takes advantage of two services that are present on most networks:
DHCP (Dynamic Host Configuration Protocol) - The standard is a means of providing IP
addresses dynamically to devices on a network.
