ANSI TR-20-1998 pdf download Fibre Channel – Fabric Loop Attach (FC-FLA)
3.1.15 Loop Tenancy: The period of time beginning when an L Port send or receives OPN and ending when an L Port has both transmitted CLS and received CLS.
3.1.16 N_ Port: As defined in FC-PH. In this report, an N_ _Port is assumed to always refer to a direct fabric-attached port, and does not include NL Ports.
3.1.17 NL Port: An L Port that is able to perform the function of an N_ Port, attached via a link to one or more NL_ Ports and zero or more FL_ Ports in an Arbitrated Loop topology. In this report, an NL_ Port is assumed to always refer to a loop-attached port, and does not include N_ Ports.
3.1.18 Name Service: A specific Fibre Channel Service provided by the Directory Server. This Service is indicated by an FCS_ Subtype of hex ’02’. See reference [6] and reference [12].
3.1.19 OPN Originator: The L Port on an Arbitrated Loop that enters the OPEN state.
3.1.20 OPN Recipient: The L_ Port on an Arbitrated Loop that enters the OPENED state. 3.1.21 Physical Loop: An Arbitrated Loop as defined in the FC-AL standard. It is useful to note that a Physical Loop can be thought of as a set of devices and the interconnects between them arranged such that any appropriate FC-PH or FC-AL frame or primitive may be sent from one device, pass through every device once, and then return to the sending device. What is important is the loop functionality, rather than the nature of the physical interconnect and routing between the devices.
3.1.22 Private Loop device: As defined in FC-PLDA.
3.1.23 Private NL_ Port: An NL_ Port that is observing the rules of Private Loop behavior (see clause 4).
3.1.24 Public Loop device: As defined in FC-PLDA.
3.1.25 Public NL_ Port: An NL_ Port that can observe the rules of either Public Loop or Private Loop behavior (see clause 4). A Public NL_ Port may have open Exchanges with both Private and Public NL Ports concurrently.
3.1.26 Query: Any of the “Get” service requests provided by the Name Service (see annex A).
3.1.27 Remote Loop: The Physical Loop separate from the Local Loop to which the other communicating NL Port is directly attached. A Remote Loop can only be reached across the Fabric.
3.1.28 Remote Port: Any NL_ Port not connected to the Local Loop, or any N_ Port. A Remote Port can only be reached across the Fabric. An NL Port can reach a Remote Port only via an OPN of AL_ _PA hex ’00’. All NL Ports and NL_ Ports are Remote Ports relative to a given N_ Port.
3.1.29 X.500 Service: A specific Fibre Channel Service provided by the Directory Server. This Service is indicated by an FCS_ Subtype of hex ’01’. See reference [6]. 3.2 Editorial conventions In this Technical Report, a number of conditions, mechanisms, sequences, parameters, events, states, or similar terms that do not have their normal English meaning are printed with the following conventions:
