FBC Firmware blade compatibility errors with the control processor (CP).
FCIP Fibre Channel over IP port configuration messages over the Brocade 7500 and FR4-18i blade.
FCMC Fibre Channel miscellaneous messages relate to problems with the physical layer used to send Fibre
Channel traffic to and from the switch.
FCOE FCoE error messages indicate problems with the FCoE module of the Fabric OS.
FCPD The Fibre Channel Protocol daemon is responsible for probing the devices attached to the loop port.
Probing is a process the switch uses to find the devices attached to the loop ports and to update the
Name Server with the information.
FCPH The Fibre Channel Physical Layer is used to send Fibre Channel traffic to and from the switch.
FCR Fibre Channel router-related traffic and activity on the fabric or back-end fabric.
FICON The FICN messages are generated during FICON emulation processing on an FCIP Tunnel.
FICON CUP FICU messages indicate that something has occurred that affects the control unit port (CUP) for the
switch or director. These messages can mean anything from configuration-related failures to internal
software errors.
FICU The FICON-CUP daemon handles communication with fibre connectivity (FICON) on IBM FICON
storage devices. Errors to this module are usually initiation errors or indications that FICON-CUP
prerequisites have not been met, such as a license key, core process ID (PID), and secure mode on
the fabric.
FKLB Fabric OS I/O kernel library module.
FLOD FLOD is a part of the fabric shortest path first (FSPF) protocol that handles synchronization of the link
state database (LSDB) and propagation of the link state records (LSRs).
FSPF Fabric shortest path first (FSPF) is a link state routing protocol that is used to determine how frames
should be routed. These messages are about protocol errors.
FSS The Fabric OS state synchronization framework provides facilities by which the active control
processor (CP) can synchronize with the standby CP, enabling the standby CP to take control of the
switch nondisruptively during failures and software upgrades. These facilities include version
negotiation, state information transfer, and internal synchronization functions, enabling the
transition from standby to active operation.
FSS is defined both as a component and a service. A component is a module in the Fabric OS,
implementing a related set of functionality. A service is a collection of components grouped together
to achieve a modular software architecture.
FSSM The Fabric OS state synchronization management module is defined both as a component and a
service. A component is a module in Fabric OS, implementing a related set of functionality. A service
is a collection of components grouped together to achieve a modular software architecture.
FW FW is the Fabric Watch module. This module monitors thresholds for many switch subsystems; for
example, temperature, voltage, fan speed, and switch status. Any changes that cross a specified
threshold are reported to the system message log.
HAM HAM is a user-space daemon responsible for high availability management.
HAMK This is the kernel module for the high availability management (HAM) daemon.
HIL Hardware independent layer.
HLO HLO is a part of the fabric shortest path first (FSPF) protocol that handles the HELLO protocol
between adjacent switches. The HELLO protocol is used to establish connectivity with a neighbor
switch, to establish the identity of the neighbor switch, and to exchange FSPF parameters and
capabilities.
