This publication lists and describes system error messages for the router and communication server products, and the protocol translator feature. The system software sends these error messages to the console (and, optionally, to a logging server on another system) during operation. Not all system error messages indicate problems with your system. Some are purely informational, while others may help diagnose problems with communications lines, internal hardware, or the system software.
System error messages begin with a percent sign and are structured as follows:
%FACILITY-SEVERITY-MNEMONIC: Message-text
FACILITY is a code consisting of two or more uppercase letters that indicate the facility to which the message refers. A facility can be a hardware device, a protocol, or a module of the system software. Table 1 lists the system facilities codes.
SEVERITY is a single-digit code from 0 to 7 that reflects the severity of the condition. The lower the number, the more serious the situation. Table 2 lists the severity levels.
MNEMONIC is a code that uniquely identifies the error message.
Message-text is a text string describing the condition. This portion of the message sometimes contains 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 3 lists the representations of variable fields and the type of information in them.
The following is a sample system error message:
%LINK-2-BADVCALL: Ints. TDR=[dec]
The "System Error Messages" main section provides descriptions of error messages organized according to the particular system facility that produces the messages. The facilities sections appear in alphabetical order, and within each system facility section, messages are listed alphabetically by mnemonic. Each error message is followed by an explanation and a recommended action. If several error messages share the same explanation and recommended action, the messages are presented as a group followed by the common explanation and recommended action.
The last main section, "Miscellaneous Error Messages," covers error messages that cannot be categorized as system error messages because they appear when the system image crashes. System error messages appear only when the system remains operational.
The index of system error messages is alphabetized by facility-severity-mnemonic.

Error message severity levels correspond to the keywords assigned by the logging global configuration commands that define where and at what level these messages appear. The default is to log messages to the console at the debugging level (7). For more information, see the system configuration chapter and descriptions of the logging command in the appropriate configuration guide and command reference publications.
