Note:
If the controller and devices are in the same LAN, subnet and VLAN, skip this step. In this scenario, the controller can discover the
devices directly, and no additional settings are required.
Make sure that the controller can discover the devices.
When the controller and devices are in different LANs, subnets or VLANs, the controller cannot discover
the devices directly. You need to choose
Controller Inform URL
,
Discovery Utility
, or
DHCP Option 138
as the method to help the controller discover the devices.
Controller Inform URL
Controller Inform URL informs the devices of the controller’s URL or IP address. Then the devices
make contact with the controller so that the controller can discover the devices.
You can configure Controller Inform URL for devices in Standalone Mode. Let’s take a switch for
example. Log into the management page of the switch in Standalone Mode and go to
SYSTEM
>
Controller Settings
to load the following page. In
Controller Inform URL
, specify Inform URL/
