NetBackup communicates between computers by using a combination of registered and dynamically allocated ports. Use the Port Ranges properties to determine how hosts connect to one another. The Port Ranges properties apply to selected master servers, media servers, and clients.
The following items describe the different types of ports:
Registered ports are registered with the Internet Assigned Numbers Authority (IANA) and are permanently assigned to specific NetBackup services. For example, the port for the NetBackup client service (bpcd) is 13782.
The following system configuration file can be used to override the default port numbers for each port:
%systemroot%\system32\drivers\etc\services
Dynamically-allocated ports are assigned as needed, from configurable ranges in the Port Ranges host properties for NetBackup servers and clients.
In addition to the range of numbers, you can configure whether NetBackup selects a port number at random or starts at the top of the range and uses the first one available.
The following topics describe the Port Ranges host properties.
