Trace dumps
The Network OS produces trace dumps when problems are encountered within Network OS
modules. The Network OS trace dump files are intended for support personnel use only. You can
use the copy support command to collect trace dump files to a specified remote location to provide
support when requested.
Using the copy support command
The copy support command is used to send the output of the system messages (RASLog), the trace
files, and the output of the copy support command to an off-switch storage location through FTP or
SCP. You can upload supportsave data from the local switch to an external host or you can save the
data on an attached USB device. The copy support command runs a large number of dump and
show commands to provide a global output of the status of the switch. Refer to the Network OS
Command Reference for more information on the copy support command.

Description
AUTH Authentication error messages indicate problems with the authentication module of the Network OS.
C2 Condor2 error messages indicate problems with the Condor2 ASIC driver module of the Network OS.
DCM Distributed Configuration Manager (DCM) messages indicate major switch bootup events, user login
or logout, and the configuration operations.
DOT1 DOT1 error messages indicate problems with the 802.1x authentication module of the Network OS.
EANV EANV module messages indicate any issues associated with eAnvil ASIC operation and eAnvil ASIC
driver operations.
ELD End Loop Detection (ELD) messages indicate 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.
FABR The FABR (network of Fibre Channel switches) error 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.
FCOE FCoE error messages indicate problems with the Fibre Channel over Ethernet (FCoE) module of the
Network OS.
FVCS The Fabric Services VCS (FVCS) daemon provides fabric distribution services for Virtual Cluster Switch
(VCS) and Virtual Link Aggregation Group (vLAG).
