Property

Description

Use random port assignments

Specifies how the selected computer chooses a port when it communicates with NetBackup on other computers. Enable this property to let NetBackup randomly select ports from those that are free in the allowed range. For example, if the range is from 1023 through 5000, it chooses randomly from the numbers in this range.

If this property is not enabled, NetBackup chooses numbers sequentially, not randomly. NetBackup starts with the highest number that is available in the allowed range. For example, if the range is from 1023 through 5000, NetBackup chooses 5000. If 5000 is in use, port 4999 is chosen.

This property is enabled by default.

Client port window

Select Use OS selected non-reserved port to let the operating system determine which non-reserved port to use.

Or, select the range of non-reserved ports on the selected computer. NetBackup can use any available port within this range as the source port when communicating with NetBackup on another computer.

Server port window

This property specifies the range of non-reserved ports on which NetBackup processes on this computer accept connections from NetBackup when the connection is not to a well known port. This property primarily applies to bpcd call-back when vnetd is disabled in the connect options and the local host name is configured for non-reserved ports.

This property also applies in the situation where a third-party protocol is used, such as NDMP. It specifies the range of non-reserved ports on which this server accepts NetBackup connections from other computers. The default range is 1024 through 5000.

Instead of indicating a range of ports, you can enable Use OS selected non-reserved port to let the operating system determine which non-reserved port to use.

This setting applies to the selected primary or media server.

Server reserved port window

This entry specifies the range of local reserved ports on which this computer accepts connections from NetBackup when the connection is not to a well known port. This property primarily applies to bpcd call-back when vnetd is disabled in the connect options for a local host name.

Instead of indicating a range of ports, you can enable Use OS selected non-reserved port to let the operating system determine which non-reserved port to use.
