FABS FABS messages indicate problems in the fabric system driver module.
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 Fibre Channel over Ethernet (FCoE) module of
the Network OS.
FCPH The Fibre Channel Physical Layer is used to send Fibre Channel traffic to and from the switch.
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. FSPF messages are about protocol errors.
FSS The fabric state synchronization framework provides facilities by which the active management
module can synchronize with the standby management module, enabling the standby
management module 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 Network OS,
implementing a related set of functionality. A service is a collection of components grouped
together to achieve a modular software architecture.
FVCS The Fabric Services VCS (FVCS) daemon provides fabric distribution services for VCS and Virtual
Link Aggregation Group (vLAG).
FW FW messages indicate the warnings when the temperature, voltage, fan speed, and switch status
thresholds are exceeded for the switch subsystems.
HASM HASM is the infrastructure for the High Availability System Management, which has the
functionality to maintain the cluster of high availability switch platforms, deploy and start multiple
service instances with active and standby redundancy in a distributed clustering environment,
manage the state synchronizations, and the non-disruptive failovers between active and standby
management modules, host the non-disruptive firmware upgrade context, and support the
software watchdog and daemon restart.
HAWK HAWK is a component that connects the fabric ASIC.
HIL HIL messages indicate any issues associated with the Hardware Independent Layer (HIL) for
general platform components, such as Environmental Monitoring (EM), fan and power supply unit
(PSU) subsystems, and other platform FRUs.
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.
HSL HSL messages indicate problems with the Hardware Subsystem Layer (HSL) of the Network OS.
HWK2 HWK2 is a component that connects the fabric ASIC.
IGMP IGMP messages indicate any issue associated with the Internet Group Management Protocol
(IGMP) snooping feature.
IPAD IPAD messages are generated by the IP admin demon.
KTRC KTRC messages indicate any problem associated with the RAS-TRACE facility, which provide
Brocade internal information to diagnose a failure.
