Working with controlled APs
Discovery of controlled APs
Discovery priority is set on a service controller using the Discovery priority of this
controller option on the Service Controller >> Management > Device Discovery page.
If two service controllers have the same high-priority setting, the AP will appear on the
Overview > Discovered APs page of both service controllers with a Diagnostic value of
Priority Conflict. To resolve the conflict, change the priority setting of one of the service
controllers on its Discovery page.
Discovery behavior
Discovery occurs differently for unprovisioned and provisioned APs.
Unprovisioned APs
Once an unprovisioned AP has received its IP address from a DHCP server (either from the
service controller-based DHCP or the corporate DHCP), it attempts to discover a service
controller using the following methods, in order:
UDP broadcast
DHCP
DNS.
These discovery methods are applied on the following interfaces, in order:
Last interface on which a service controller was discovered. (Only applies to APs that
have previously discovered a service controller)
Untagged on Port 1
All other detected VLANs (in sequence) on Port 1.
Provisioned APs
The discovery method that is used depends on how the AP is provisioned. If discovery
settings are provisioned, then the AP uses only the provisioned settings. The following
discovery options are available:
DNS discovery: Enables custom service controller names and domains to be used for
discovery.
