System module descriptions
provides a summary of the system modules for which messages are documented in this
reference guide; a module is a subsystem in the Network OS. Each module generates a set of
numbered messages.

Description
AG
Access Gateway (AG) allows multiple hosts (or HBAs) to access the fabric using fewer physical
ports. Access Gateway mode transforms the Brocade switches as well as embedded switches into
a device management tool that is compatible with different types of fabrics.
AUTH
AUTH messages indicate problems with the authentication module of the Network OS.
BGP
BGP messages indicate problems with the Border Gateway Protocol (BGP) module of the Network
OS.
BL
BL messages are a result of faulty hardware, transient out-of-memory conditions, ASIC errors, or
inconsistencies in the software state between an interface module and the environment monitor
(EM) module.
BLL
Bloom is the name of the ASIC used as the building block for third-generation hardware platforms.
C2
C2 error messages indicate problems with the 8 Gbps-capable FC module of the Network OS.
C3
C3 error messages indicate problems with the 16 Gbps-capable FC module of the Network OS.
CBR
CBR error messages indicate problems with the ASIC driver of Network OS.
CHS
CHS messages report the problems in the management of the interface modules in the different
slots of the chassis.
DAD
DAD messages report errors encountered during the DHCP Auto Deployment (DAD) process.
DCM
Distributed Configuration Manager (DCM) messages indicate major switch bootup events, user
login or logout, and the configuration operations.
DOT1
DOT1 messages indicate problems with the 802.1x authentication module of the Network OS.
EANV
EANV messages indicate any issues associated with eAnvil ASIC operation and eAnvil ASIC driver
operations.
ELD
End Loop Detection (ELD) messages notify a loop in the Layer 2 network and the status of the port
on which the loop is detected.
EM
The environmental monitor (EM) manages and monitors the various field-replaceable units (FRUs),
including the port cards, blower assemblies, power supplies, and World Wide Name (WWN) cards.
EM controls the state of the FRUs during system startup, hot-plug sequences, and fault recovery.
EM provides access to and monitors the sensor and status data from the FRUs and maintains the
integrity of the system using the environmental and power policies. EM reflects system status by
way of CLI commands, system light emitting diodes (LEDs), and status and alarm messages. EM
also manages some component-related data.
ERCP
ERCP messages indicate any problems associated with Double Data Rate (DDR) errors.
ESS
Exchange Switch Support (ESS) error messages indicate problems with the ESS module of the
Network OS. ESS is an SW_ILS mechanism utilized by switches to exchange vendor and support
information.
FABR
FABR (network of Fibre Channel switches) messages come from the fabric daemon. The fabric
daemon follows the FC-SW-3 standard for the fabric initialization process, such as determining the
E_Ports, assigning unique domain IDs to switches, creating a spanning tree, throttling the trunking
process, and distributing the domain and alias lists to all switches in the fabric.
