11Directors and Edge Switches Glossary
error message
Software message that indicates an error was detected. See also information message and
warning message.
Ethernet
A widely implemented local area network (LAN) protocol that uses a bus or star topology and
serves as the basis for the IEEE 802.3 standard, which specifies the physical and software
layers. Baseband LAN allows multiple station access to the transmission medium at will
without prior coordination and which avoids or resolves contention.
Ethernet hub
A customer-supplied device used to LAN-connect the HAFM server and the directors it
manages.
event code
A three-digit numeric code that displays in the event log and identifies a specific event that
occurred. This code provides information on system failures, such as hardware failures; failure
locations; or general information on normal system events.
event log
Record of significant events that have occurred at the director or switch or through the HAFM
Management Services application, such as FRU failures, degraded operation, and port problems.
expansion port
(E_Port) — Physical interface on a Fibre Channel switch within a fabric that attaches to an
expansion port (E_Port) on another Fibre Channel switch to form a multiswitch fabric. See also
segmented E_Port.
explicit fabric login
Data field size, supported by an F_Port, that is agreed upon during fabric login.
fabric
Fibre Channel entity that interconnects node ports (N_Ports) and is capable of routing
(switching) Fibre Channel frames using the destination ID information in the Fibre Channel
frame header accompanying the frames.
fabric address notification
(FAN) — A message that informs all NL_Ports of the address of the FL_Port. Allows LIP
processing to not be disruptive to FC traffic on devices that support FAN. See also loop
initialization primitive.
fabric element
An active switch, director, or node in a Fibre Channel switched fabric.
