XPath OS 7.4.x MIB reference guide 59
port address
In Fibre Channel technology, the port address is defined in hexadecimal. In the HP Fabric OS, a port
address can be defined by a domain and port number combination or by area number. In an ESCON
Director, an address used to specify port connectivity parameters and to assign link addresses for attached
channels and control units.
port card
A hardware component that provides a platform for field-replaceable, hot-swappable ports.
port log
A record of all activity on a switch, kept in volatile memory.
port log dump
A view of what happens on a switch, from the switch's point of view. The portLogDump command is used
to read the port log.
port name
A user-defined alphanumeric name for a port.
port swapping
Port swapping is the ability to redirect a failed port to another port. This feature is available in Fabric OS
v4.1.0 and later.
port_name
The unique identifier assigned to a Fibre Channel port. Communicated during login and port discovery.
primitive sequence
An ordered set that is transmitted repeatedly and continuously. Primitive sequences are transmitted to
indicate specific conditions within or conditions encountered by the receiver logic of an FC_Port.
principal switch
The first switch to boot up in a fabric. Ensures unique domain IDs among roles.
private NL_Port
An NL_Port that communicates only with other private NL_Ports in the same loop and does not log in to the
fabric.
protocol
A defined method and set of standards for communication. Determines the type of error-checking, the
data-compression method, how sending devices indicate an end of message, and how receiving devices
indicate receipt of a message.
PSU
Power supply unit.
public loop
An arbitrated loop that includes a participating FL_Port and can contain both public and private NL_Ports.
public NL_Port
An NL_Port that logs in to the fabric and can function within either a public or a private loop and can
communicate with either private or public NL_Ports.
radius
The greatest distance between any edge switch and the center of a fabric. A low-radius network is better
than a high-radius network.
