Access Point Adoption Overrides (Access Points Only)

Adoption is the process an access point uses to discover an available controller or service platform, pick the most desirable one, establish an association and optionally obtain an image upgrade and configuration. Adoption settings are configurable and supported within a device profile and applied to other access points supported by the profile. Individual attributes of an access point's auto provisioning policy can be overridden as specific parameters require modification.

At adoption, an access point solicits and receives multiple adoption responses from controllers and service platforms available on the network. These adoption responses contain loading policy information the access point uses to select the optimum controller or service platform for adoption. By default, an auto provisioning policy generally distributes AP adoption evenly amongst available controllers and service platforms. Modify existing adoption policies or create a new one as needed to meet access point adoption requirements and profile settings.

Note

A device configuration does not need to be present for an auto provisioning policy to take effect. Once adopted, and the device's configuration is defined and applied by the controller, the auto provisioning policy mapping does not have an impact on subsequent adoptions by the same device.

An auto provisioning policy enables an administrator to define adoption rules for access points capable of being adopted by a controller or service platform.

To define an access point's adoption configuration or apply an override:

1. Select the Devices from the Web UI.
2. Select Profiles from the Configuration tab.
3. Select Profile Overrides to expand its sub-menu items.
4. Select Adoption.

   A screen displays where an access point's adoption configuration can be defined and overridden for a profile.

   

   Note

   A blue override icon (to the left of a parameter) defines the parameter as having an override applied. To remove an override go to the Basic Configuration section of the device and click the Clear Overrides button. This removes all overrides from the device.

   

5. Define or override the Preferred Group used as optimal group of controllers for the access point's adoption. The name of the preferred group cannot exceed 64 characters.
6. Set the following Controller Hello Interval settings manage message exchanges and connection re-establishments between adopting devices:

   Hello Interval	Define an interval (from 1 - 120 seconds) between hello keep alive messages exchanged with the adopting device. These messages serve as a connection validation mechanism to ensure the availability of the adopting resource.
   Adjacency Hold Time	Set the time (from 2 - 600 seconds) after the last hello packet after which the connection between the controller and access point is defined as lost and their connection is re-established. When a hello interval is set, an adjacency hold time is mandatory and should be higher then the hello interval.

7. Select this option to define or override the VLAN the access point's associating controller or service platform is reachable on.

   VLANs 0 and 4,095 are reserved and cannot be used by a VLAN.

8. Enter Controller Hostnames as needed to define or override resources for access point adoption.

   Select + Add Row as needed to populate the table with IP Addresses or Hostnames of controllers used as access point adoption resources into the managed network.

   Host	Use the drop-down menu to specify whether the controller adoption resource is defined as a (non DNS) IP Address or a Hostname. Once defined, provide the numerical IP or Hostname. A Hostname cannot exceed 64 characters.
   Pool	Use the spinner control to set a pool of either 1 or 2.
   Routing Level	Define a routing level (either 1 or 2) for the link between adopting devices. The default setting is 1.
   IPSec Secure	Enable this option to provide IPSec secure peer authentication on the connection (link) between the adopting devices. This option is disabled by default
   IPSec GW	Select the numerical IP address or administrator defined hostname of the adopting controller resource.
   Force	Enable this setting to create a forced link between an access point and adopting controller, even when not necessarily needed. This setting is disabled by default.
   Remote VPN Client	Displays whether a secure controller link has been established using a remote VPN client.

9. Select OK to save the changes and overrides made to the access point profile adoption configuration. Select Reset to revert to the last saved configuration.
