Chapter 1 Introduction to System Messages for the Cisco MDS 9000 Family
System Log Message Format
FACILITY is a code consisting of two or more uppercase letters that indicate the facility to which the
system message refers. A facility is a hardware device, a protocol, a feature, or a module of the system
software.
System message
SEVERITY codes range from 0 to 7 and reflect the severity of the condition. The lower
the number, the more serious the situation. Table 1-1 lists the severity levels.
MNEMONIC is a code that uniquely identifies the system message.
Message-text is a text string that describes the condition. This portion of the message might contain
detailed information about the event, including terminal port numbers, network addresses, or addresses
that correspond to locations in the system memory address space. Because the information in these
variable fields changes from message to message, it is represented here by short strings enclosed in
square brackets (
[]). A decimal number, for example, is represented as [dec].
Table 1-2 lists the representations of variable fields and the type of information in the fields.
severity Single-digit code from 0 to 7 that indicates the severity of the message
