What are the default CONNECT_OPTIONS for Netbackup servers.

The CONNECT_OPTIONS and DEFAULT_CONNECT_OPTIONS configuration values determine how the local computer connects to services on other NetBackup systems. The values for CONNECT_OPTIONS are a host name followed by three digits. The values for DEFAULT_CONNECT_OPTIONS are three digits.

CONNECT_OPTIONS = host 0|1|2 0|1|2 0|1|2|3

and

DEFAULT_CONNECT_OPTIONS = 0|1 0|10|1|2

■ host is a remote NetBackup system that the local computer connects to. You may have multiple CONNECT_OPTIONS entries in the configuration. If a host is not specified in any CONNECT_OPTIONS entries, the values from the DEFAULT_CONNECT_OPTIONS entry are used.

■ The first digit is the reserved versus non-reserved source port:

■ 0 means that connections to bpcd from the local computer should use a reserved source port number selected from the CLIENT_RESERVED_PORT_WINDOW range. (Default.)

■ 1 means that connections to bpcd from the local computer should use a non-reserved source port number selected from the CLIENT_PORT_WINDOWrange. Be sure ALLOW_NON_RESERVED_PORTS = YES is set on the remote hosts that the local computer may connect
to.

■ 2 when specified in CONNECT_OPTIONS means that the value from DEFAULT_CONNECT_OPTIONS should be used instead.

■ The second digit is bpcd call-back method:

■ 0 means that for connections to bpcd from the local computer, bpcd will connect back to a random port number on the local computer selected from the SERVER_RESERVED_PORT_WINDOW range or SERVER_PORT_WINDOW range on the server. (Default for 5.1and earlier.)

■ 1 means that for connections to bpcd from the local computer, bpcd will connect back to the vnetd port number on the server. (Default)

■ 2 when specified in CONNECT_OPTIONS means that the value from DEFAULT_CONNECT_OPTIONS should be used instead.

■ The third digit is the legacy versus vnetd destination port:

■ 0 means that the local computer will first attempt to connect to a NetBackup service using the vnetd destination port number. If that fails, the local computer will attempt to connect to the NetBackup service using the legacy destination port number for that service. (Default)

■ 1 means that connections to a NetBackup service from the local computer use the vnetd destination port number.

■ 2 means that connections to aNetBackup service from the local computer use the legacy destination port number for the service.

■ 3 when specified in CONNECT_OPTIONS means that the value from DEFAULT_CONNECT_OPTIONS should be used instead.

Note: vnetd can only be used as the destination port if the remote host is not a NetWare client.

If vnetd is used as the destination port, the settings from the first two digits are not applicable. In that case, the source port will be from the non-reserved
CLIENT_PORT_WINDOW range and no connect back will be used.

Example: The connection options to most remote hosts from the local computer will use the NetBackup defaults. 

 

Legacy versions or upgrades from those versions may have the following values:

CONNECT_OPTIONS = servers 0 10
DEFAULT_CONNECT_OPTIONS = 0 0 2

In this case the DEFAULT_CONNECT_OPTIONS should be changed to:

DEFAULT_CONNECT_OPTIONS = 0 1 0

These settings can be configured in the  NetBackup Administration GUI via the HostProperties Ø Firewall panel.
