802 Glossary
end-to-end flow
control
Governs flow of Class 1 and 2 frames between N_Ports. See also EE_Credit .
entry fabric The basic HP software license that allows one E_Port per switch.
EOF End of frame. A group of ordered sets used to mark the end of a frame.
error As it applies to the Fibre Channel industry, a missing or corrupted frame, timeout, loss of
synchronization, or loss of signal (link errors). See also loop failure .
EVMd Event management database. Delivers FDMI-related events.
EX_Port A type of E_Port that connects an FC router to an edge fabric. EX_Ports limit the scope of
fabric services scope but provide device connectivity using FC-NAT.
exchange The highest-level Fibre Channel mechanism used for communication between N_Ports.
Composed of one or more related sequences, it can work in either one or both directions.
exported device A device that has been mapped between fabrics (a host or storage port in one edge fabric
can be exported to any other fabric by using LSAN zoning).
F_BSY Fabric port busy frame. A frame issued by the fabric to indicate that a frame cannot be
delivered because the fabric or destination N_Port is busy.
F_Port Fabric port. A port that is able to transmit under fabric protocol and interface over links. Can
be used to connect an N_Port to a switch. See also FL_Port , Fx_Port .
F_RJT Fabric port reject frame. A frame issued by the fabric to indicate that delivery of a frame is
being denied, perhaps because a class is not supported, there is an invalid header, or no
N_Port is available.
fabric A collection of Fibre Channel switches and devices, such as hosts and storage. Also referred to
as a switched fabric . See also cascade , SAN , topology .
fabric application
platform
A device that enables fabric-based storage applications such as mirroring, data migration,
snapshots, and virtual tape. The HP StorageWorks Fabric Application Platform can run in a
central location, process data at wire-speed, and reside in existing data paths.
Fabric Manager An optionally licensed HP software. Fabric Manager is a GUI that allows for fabric-wide
administration and management. Switches can be treated as groups, and actions such as
firmware downloads can be performed simultaneously.
Fabric Mode One of two possible modes for an L_Port, in which the L_Port is connected to another port that
is not loop capable, using fabric protocol.
fabric name The unique identifier assigned to a fabric and communicated during login and port discovery.
fabric port count The number of ports available for connection by nodes in a fabric.
fabric services Codes that describe the communication to and from any well-known address.
fabric topology The arrangement of switches that form a fabric.
Fabric Watch An optionally licensed HP software. Fabric Watch can be accessed through either the
command line or Advanced Web Tools, and it provides the ability to set thresholds for
monitoring fabric conditions.
failover Describes the Core Switch 2/64 process of one CP passing active status to another CP. A
failover is nondisruptive.
