What it Means

The messages system log file records the time the failure or event occurred, the severity level, a code, and a message description. You can also use the show log messages | match sib command to see error messages that are generated when an SIB fails or is offline. Use this information to diagnose an SIB problem and to let the Juniper Networks Technical Assistance Center (JTAC) know what error messages were generated and the router events that occurred before and after the problem.
