Ensuring That APs Can Discover the Controller on the Network
Method 3: Register the Controller with the DNS Server
Figure 37. Insert option domain-name "38.jack"
4 Save the DHCP configuration file.
When the AP obtains the DNS domain name from the DHCP server (using "Domain
Name option 15" in the DHCP-offer packet), it will resolve
"RuckusController.{domain-name}" and "zonedirector.{domain-name}" through the
DNS server, and then it will obtain the controller's IP address from the DNS server's
response.
NOTE: If the AP uses a static IP address or it cannot obtain the DNS domain name
from the DHCP server, the AP will attempt to resolve "RuckusController" and
"zonedirector" without a domain name from the DNS server as the FQDN of
controller's control interface.
You have completed registering the controller with the DNS server.
