NetBackup default ports

NetBackup primarily uses the ports as destination ports when connecting to the various services.

See Table: NetBackup ports.

Veritas has registered these ports with Internet Assigned Number Authority (IANA) and they are not to be used by any other applications.

A few features and services of NetBackup require additional ports to be open. Those requirements are detailed in later sections.

By default, NetBackup uses ports from the non-reserved range for the source port. Those ports are selected randomly from the range provided by the operating system.


Configuring the Connect Options and other settings may change how source and destination ports are selected. These settings and other non-default configurations, are not discussed here. For details, see the NetBackup Administration Guides, volume 1 and volume 2.

The following table lists the ports required by NetBackup to connect to various services.
