Port Ranges properties
The Port Ranges properties can be configured on the NetBackup web UI. On the left pane, select . Depending on the host to be configured, select the Primary Server, Media Servers, or Clients. From the Actions menu, select the option, and then click .
Use the Port Ranges properties in the NetBackup Administration Console to determine how hosts connect to one another. These properties apply to selected primary servers, media servers, and clients.
The Port Ranges dialog box contains the following properties.

Property | Description |
|---|
| 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. |
| Lets the administrator define 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. |
| Lets the operating system determine which non-reserved port to use. |
| This setting defines the range of reserved ports to use as the source port for the connection to NetBackup services. (By default, a NetBackup host uses a non-reserved port to connect to destination host names.) If the following conditions are true, NetBackup chooses a port from the specified range: The destination host name is local to the connecting host. The local host name configuration uses a reserved port for the source port rather than a non-reserved port. The destination port is a daemon port. The local host name uses a daemon port for the destination if one of the following is true: The destination connect option for the local host name specifies that a daemon port be used. Attempts to connect to destination ports 1556 and 13274 on the local host fail, which causes the daemon port to be used.

| 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.
The Accept connections on non reserved ports property must be
enabled in the Universal Settings dialog box for hosts running NetBackup 7.0.1 and prior versions. See Universal Settings properties. |

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. |
