Enabling or disabling random port assignments
The property specifies how the selected computer chooses a port when it communicates with NetBackup on other computers, as follows:
When enabled, NetBackup chooses port numbers randomly from those that are free in the allowed range. For example, if the range is from 1023 through 5000, it chooses from the numbers in this range. This is the default behavior.
When disabled, NetBackup chooses numbers sequentially, starting with the highest number that is available, in the allowed range. For example, if the range is from 1023 through 5000, NetBackup chooses 5000, assuming that it is free. If 5000 is used, NetBackup chooses port 4999.
The port selection scheme must be the same on the master server and on all media servers. By default, NetBackup assigns ports randomly. If you change one of your computers to use sequential port assignments, make sure to change all the computers in your environment to use sequential port assignments.
The following procedure explains how to specify port assignments.
To specify port assignments from the NetBackup Administration Console
- In the NetBackup Administration Console, expand one of the following:
To specify a master server's port assignments, expand NetBackup Management > Host Properties > Master Servers
To specify a media server's port assignments, expand NetBackup Management > Host Properties > Media Servers
- Double click the host you want to configure.
- Click Port Ranges.
- Check or clear Use random port assignments.
Make sure that the master server and the media servers in your environment are set identically. That is, make sure that Use random port assignmentsis cleared on both systems or that Use random port assignments is checked on both systems.
