Fabric OS Reference Manual

284 Fabric OS Reference Manual
EE_Credit End-to-end credit. The number of receive buffers allocated by recipient port
to originating port. Used by Class 1 and 2 services to manage exchange of
frames across intervening ports in fabric. See also End-to-end flow control,
BB_Credit.
Enabled
configuration
The currently enabled zone configuration. Only one configuration can be
enabled at a time. See also Defined configuration, Zone configuration.
End-to-end flow
control
Governs flow of Class 1 and 2 frames between N_Ports. See also
Buffer-to-buffer flow control, EE_Credit.
Error As applies to fibre channel, a missing or corrupted frame, time-out, loss of
synchronization, or loss of signal. See also Loop failure.
Exchange As applies to fibre channel, a communication session between N_Ports
involving the transmission of one or more related sequences, in one or both
directions. See also Sequence.
Extended Fabrics Product that allows interconnection of fibre channel fabric over distances of
up to 100 kilometers.
F_Port Fabric Port. A port that can transmit using fabric protocol and can interface
over links. Can be used to connect N_Ports to a switch. See also FL_Port,
Fx_Port.
Fabric A fibre channel network of two or more switches. Also called a “switched
fabric.” See also SAN, Cascade.
Fabric name Unique 64-bit identifier assigned to each separate fabric. Communicated
during login and port discovery.
Fabric OS Proprietary operating system on switches.
Fabric Watch Product that allows monitoring and configuration of fabric and switch
elements.
FC-AL-3 The Fibre Channel Arbitrated Loop standard. Defined on top of FC-PH
standards.
FC-FLA The Fibre Channel Fabric Loop Attach standard.
FCP Fibre Channel Protocol. Mapping of protocols onto fibre channel standard
protocols. For example, SCSI FCP maps SCSI-3 onto fibre channel.
