Connecting a Set of IoT APs Using a Grouping Method

There are two methods to determine which set of IoT APs to connect with the IoT Controller:

• Isolate the IoT APs and non-IoT APs at Layer 2 (VLAN) or Layer 3 (IP) subnets. In this case, DHCP option 43 suboption 21 can be configured for networks with APs meant to connect with a particular IoT Controller. The syntax of suboption 21 is the same as suboption 6 for the Wi-Fi Controller.

• If network topology cannot be used for grouping, e.g., as a result of customer’s network topology policies, the second method to use is static configuration method:
  Note: Running set-iotg-mqtt-broker ip cli script is not recommended for the AP's already connected to the IoT controller.
  • Disable IoT processes on all APs.
  • Enable IoT processes only on IoT-enabled APs.
  • Set the IoT Controller IP address on the IoT-enabled APs.

The static configuration method can be accomplished using a vSZ AP CLI script. For example, in vSZ, you create a zone for the group of IoT-enabled APs that you want to connect to a particular IoT Controller. You then apply the vSZ AP CLI script to the zone that enables IoT (set iotg-enable 1) and set the IoT Controller IP address with the set iotg-mqtt-brokerip ip-address command.
