Configuring the syslog message destinations

You can configure the Fabric OS to send the syslog messages to the following output locations:
syslog daemon, system console, and SNMP management station.

System logging daemon

The system logging daemon (syslogd) is a process on UNIX, Linux, and some Windows systems that
reads and logs messages as specified by the system administrator.
Fabric OS can be configured to use a UNIX-style syslogd process to forward system events and error
messages to log files on a remote host system. The host system can be running UNIX, Linux, or any
other operating system that supports the standard syslogd functionality. Configuring for syslogd
involves configuring the host, enabling syslogd on the Brocade model, and, optionally, setting the
facility level.
For the Brocade DCX family of switches, each control processor (CP) has a unique error log,
depending on which CP was active when that message was reported. To fully understand message
logging, you should enable the syslogd, because the logs on the host computer are maintained in a
single merged file for both CPs and are in sequential order. Otherwise, you must examine the error
logs in both CPs, particularly for events such as firmwareDownload or haFailover, for which the
active CP changes.
For the Brocade DCX family of switches, any security violations that occur through Telnet, HTTP, or
serial connections are not propagated between CPs. Security violations on the active CP are not
propagated to the standby CP counters in the event of a failover, nor do security violations on the
standby CP get propagated to the active CP counters.
Configuring a syslog server
To configure the switch to forward all system events and error messages to the syslogd of one or
more servers, perform the following steps.
1. Log in to the switch as admin.
2. Execute the syslogdIpAdd IP address command to add a server to which system messages are
3. Execute the syslogdIpShow command to verify the syslog configuration on the switch.
You can remove a configured syslog server using the syslogdIpRemove IP address command.

System console

The system console displays RASLog messages, Audit messages (if enabled), and panic dump
messages. These messages are mirrored to the system console; they are always saved in one of
the system logs.
