This completes the preparation for the “discovery” process. Now you can go back to the Altitude APs
and power them on.
Discovery and registration
When the Altitude AP is powered on, it automatically begins a “discovery” process to determine the IP
address of the Summit WM-Series Switch. When successful, it registers with the Summit WM-Series
Switch.
When the Altitude AP is registered, it appears in the Altitude AP Access Approval screen. You can check
its status in this screen. If the status is “Pending”, you must modify it to “Approved”.
You can now assign the registered and approved Altitude AP to a WM Access Domain Service (WM-
AD) and it will be ready to handle wireless traffic.
Discovery steps
The Altitude APs “discover” the IP address of a Summit WM-Series Switch using a sequence of
mechanisms that allow for the possible services available on the enterprise network.
The “discovery” steps are processed in the following order, until the Altitude AP successfully locates a
Summit WM-Series Switch with which it can “register”.
1 Use the IP address of the last successful connection to a Summit WM-Series Switch.
2 Use the predefined static IP addresses for the Summit WM-Series Switchs on the network (if so
configured).
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.
4 Use a Domain Name Server (DNS) lookup for the host name “ext-summitwm-connect-1”.
5 Use a multicast SLP request to find SLP Service Agents (SAs).
You must ensure that the appropriate services on your enterprise network are prepared to support the
“discovery” process.
Discovery step 1: last successful connection
Once a Altitude AP has successfully registered with a Summit WM-Series Switch, it remembers that
controller's IP address, and will use that address on subsequent reboots. In effect, it will bypass
discovery, and go straight on to registration. However, if this discovery method fails, it cycles through
the remaining steps until it meets with success.
Delay between Retries The default is 1 second
