Appendix B System Messages
How to Read System Messages
• 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 B-2 lists the message severity levels.
• MNEMONIC is a code that uniquely identifies the 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 B-3 lists the variable fields in messages.
This is a sample system message:
%LINK-2-BADVCALL: Interface [chars], undefined entry point
Some messages also show the card and slot reporting the error. These error messages begin with a
percent sign (%) and are structured as follows:
Error Message %CARD-SEVERITY-MSG:SLOT %FACILITY-SEVERITY-MNEMONIC: Message-text
where:
• CARD is a code that describes the type of card reporting the error.
• MSGisamnemonicthatmeansthatthisisamessage.ItisalwaysshownasMSG.
• SLOT means that the slot number of the card reporting the error. It is shown as SLOT followed by
a number. (For example, SLOT5.)
