Step 2: Display Error Messages in the System Log File

Action

To display PIC error messages in the system log file, use the following CLI command:

user@host> show log messages | match PIC

Sample Output

user@host> show log messages | match PIC

Apr  8 10:01:20 aspirin scb CM: PIC 0/2, ID 0x0206, hardware error, offlined

Apr  8 10:01:20 aspirin alarmd[2671]: Alarm set: FPC color=RED, class=CHASSIS, 
reason=PIC 0/2 failed to initialize

Apr  8 10:01:20 aspirin fpc0 PIC: PIC 2 discovery error (1)

Apr  8 10:01:21 aspirin scb CM: ALARM SET: (Major) Slot 0: PIC 0/2 failed to

What It Means

When a PIC fails, the messages system log file records the time the failure or event occurred, the severity level, a code, and a message description. Use the show log messages command to browse error messages that are generated at least 5 minutes before and after a PIC event. You can also use the show log messages | match PIC command to view specific PIC error messages with common information. Use this information to diagnose a PIC problem and to let the Juniper Networks Technical Assistance Center (JTAC) know what error messages were generated and the router events prior to the problem.
