RANDOM_PORTS entry in vm.conf
Use this entry to specify whether NetBackup chooses port numbers randomly or sequentially for communication with other NetBackup servers. This entry is read and interpreted on hosts on which vmd runs.
RANDOM_PORTS = YES|NO
If YES or no entry exists (the default), NetBackup chooses port numbers randomly from those that are available in the allowed range.
If NO, NetBackup chooses numbers sequentially. NetBackup begins with the highest number in the allowed range, and then tries the next highest, and so on until a port is available.
On UNIX, if random ports are not specified in the NetBackup configuration, specify RANDOM_PORTS = NO in the vm.conf file.
See the NetBackup Administrator's Guide, Volume I:

To specify no random ports in the NetBackup configuration file, do one of the following:
Specify RANDOM_PORTS = NO in the bp.conf file on UNIX.
Use the NetBackup Host Properties in the NetBackup Administration Console: NetBackup Management > Host Properties > Double-click on master server > Port Ranges > Use random port assignments.
