Glossary
product name
User-configurable identifier assigned to a managed product.
Typically, this name is stored on the product itself. A director or
switch product name can also be accessed by a simple network
management protocol (SNMP) manager as the system name.
prohibited port
connection
In a director or switch, in S/390 operating mode, an attribute that
removes dynamic connectivity capability.
proprietary
Privately owned and controlled. In the computer industry,
proprietary is the opposite of open. A proprietary design or
technique is one that is owned by a company. It also implies that the
company has not divulged specifications that would allow other
companies to duplicate the product. Increasingly, proprietary
architectures are seen as a disadvantage. Consumers prefer open and
standardized architectures, which allow them to mix and match
products from different manufacturers.

public device
A loop device that can transmit a fabric login command (FLOGI) to a
switch, receive acknowledgement from the switch’s login server,
register with the switch’s name server, and communicate with
fabric-attached devices. Public devices communicate with
fabric-attached devices through the switch’s bridge port (B_Port)
connection to a director or switch.
Contrast with
private device .
public loop
A public loop is connected to a switched fabric (through the switch
bridge port (B_Port)), and the switch has an active embedded fabric
loop port (FL_Port) that is user transparent. All devices attached to
the loop can communicate with each other, and public devices
attached to the loop can communicate with fabric-attached devices.
Contrast with
private loop .
