RANDOM _PORTS option for NetBackup servers and clients

This option specifies whether NetBackup chooses port numbers randomly or sequentially when it requires one for communication with NetBackup on other computers.

Table: RANDOM _PORTS information

Usage	Description
Where to use	On NetBackup master servers or clients.
How to use	Use the nbgetconfig and the nbsetconfig commands to view, add, or change the option. For information about these commands, see the NetBackup Commands Reference Guide. If RANDOM_PORTS = YES (default), NetBackup chooses port numbers randomly from those that are free in the allowed range. For example, if the range is from 1024 through 5000, it chooses randomly from the numbers in this range. If RANDOM_PORTS = NO, NetBackup chooses numbers sequentially, starting with the highest number available in the allowed range. For example, if the range is from 1024 through 5000, NetBackup chooses 5000 (if the number is available). If 5000 is not available, port 4999 is chosen. By default, this option is not present in the configuration file and NetBackup uses the random method for selecting port numbers.
Equivalent Administration Console property	NetBackup Management > Host Properties > Master Servers > Double-click on server > Port Ranges > Use random port assignments. See Port Ranges properties.
