Configure the BlackBerry Administration Service instances in a pool to communicate across network subnets

The instances in the BlackBerry® Administration Service pool use multicast UDP to communicate with each other. If the BlackBerry Administration Service instances are located in different network subnets and your organization's network configuration does not permit multicast UDP across the network subnets, you must configure the BlackBerry Administration Service instances to use TCP to communicate with each other. For example, if your organization uses a UDP peer-to-peer firewall filter, you must configure the BlackBerry Administration Service instances to use TCP to communicate across the network subnets.

  1. Make sure that no BlackBerry Administration Service instance is in the process of restarting.
  2. In the BlackBerry Administration Service, on the Servers and components menu, expand BlackBerry Solution topology > BlackBerry Domain > Component view > BlackBerry Administration Service.
  3. Click Edit component.
  4. In the BlackBerry Administration Service pool drop-down list, click TCP with TCP PING.
  5. Click Save all.
  6. Restart the BlackBerry Administration Service instances.
