Overview of system messages
This guide supports Brocade Network OS v2.1.1 and documents system messages that can help
you diagnose and fix problems with a switch or network. The guide is organized alphabetically by
module name. A module is a subsystem in the Network OS. Each module generates a set of
numbered messages. For each message, this guide provides message text, probable cause,
recommended action, and severity level. There may be more than one cause and more than one
recommended action for any given message. This guide discusses the most probable cause and
typical action recommended.
This chapter provides an introduction to system messages. The Network OS maintains an internal
system message log of all messages. All messages are tagged by type as either RASLog system
error messages, Audit messages, or both. RASLog error messages are primarily designed to
indicate and log abnormal, error-related events, whereas Audit messages record events such as
login failures, zone changes, or configuration changes. Network OS supports a different
methodology for storing and accessing each type of message.
System message types
Network OS supports four types of system messages. A system message can be of one or more of
the following types.
RASLog messages
RASLog messages report significant events or information and are also used to show the status of
the high-level user-initiated actions. RASLog messages are forwarded to the console, to the
configured syslog servers, and through the SNMP traps or informs.
