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. When the SCB fails, the
fxp1
interface keeps going up and down. You can use the
show log messages | match scb
command to see error messages that are generated when an SCB fails or is offline.
Use this information to diagnose a 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. For more information
about system log messages, see the JUNOS System Log Messages Reference.
Step 2: Display SCB Error Messages in the Chassis Daemon Log File
Action To display SCB error messages in the chassis daemon (chassisd) log file, use the
following CLI command:
user@host> show log chassisd
Sample Output
user@host>
show log chassisd
