TCPPORT (1500, default) is used by the ADSM Server to listen for
connections from the ADSM Clients.  TCPPORT+1 (1501) is used by the
ADSM Client Scheduler (dsmc schedule) when using SCHEDMODE PROMPTED to
listen for the "prompt" from the Server to initiate a scheduled
operation.

When you start up a client with SCHEDMODE PROMPTED, it contacts the
server on TCPPORT (1500) and registers its IP address.  It then
disconnects and listens on port TCPPORT+1 for the server to contact
it.

This is why, for example, if you clients use DHCP and the IP address
changes, the server will be unable to contact the client until the
dsmc schedule service is stopped and restarted.
