MSM7xx Controllers Configuration Guide v6.4.0

Discover using DNS
The AP attempts to connect with a controller using the names in the order that they appear in this
list.
To discover the controller on the network, the AP appends each name with the specified Domain
name.
In the above example, the AP will search for controllers with the names:
• service-controller-1.mydomain.com
• service-controller-2.mydomain.com
If you define a name that contains a dot, then the domain name is not appended. For example, if
the name is controller.yourdomain.com, no domain name is appended.
If the AP is operating as a DHCP client, the DHCP server will generally return a domain name
when it assigns an IP address to the AP. If you leave the Domain name field on this page blank,
then the DHCP domain name is appended to the specified names instead.
Discover using IP address
The AP attempts to connect with a controller using the IP addresses in the order that they appear
in this list.
Discovery authentication
Authentication can be enabled during the discovery process to allow a controller and AP to validate
each other prior to establishing a control channel. Authentication can be mutual, or can be
preformed only by the controller or AP, depending on how you define the configuration.
• Shared secret/Confirm shared secret: Specify the shared secret that the AP will use when
authenticating a controller or responding to an authentication request from a controller. For
a control channel to be established, the secret you define here must match the one configured
