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.

Changing the name of the BlackBerry
Administration Service pool
When you install the first BlackBerry Administration Service instance in a BlackBerry Domain, the default name of the
BlackBerry Administration Service pool is the FQDN of the computer that you perform the installation on. If you want to
configure high availability using DNS round robin after the installation process completes, you must change the name of
the BlackBerry Administration Service pool to the name of a record in the DNS server that represents the BlackBerry
Administration Service instances in the pool. You must also change the name of the BlackBerry Administration Service pool
if you have changed the name of the corresponding DNS record in the DNS server. You can only configure one BlackBerry
Administration Service pool in a BlackBerry Domain.
When you change the name of the BlackBerry Administration Service pool, you must synchronize the BlackBerry
Monitoring Service with the name of the BlackBerry Administration Service pool in the BlackBerry Configuration Database.
