Verifying CFEB Failure
The chassisd database provides the date, time, and a component status message.
The chassisd database is dynamic. It is initialized at router startup and is updated
when components are added or removed. You can search for multiple items in the
log file by using the show log chassisd | match cfeb command to see error
chassisd
messages that are generated when a Control Board fails or is offline. Use this
information to diagnose a Control Board problem and to let 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.
To verify CFEB failure, follow these steps:
1. Check the CFEB Uptime on page 426
2. Check the System Uptime on page 427
3. Check the CFEB Connection on page 427
4. Perform a Swap Test on the CFEB on page 427
To check the CFEB uptime, use the following CLI command:
user@host> show chassis cfeb
user@host> show chassis cfeb
CFEB status:

The command output displays how long the CFEB has been operating. A short
uptime can indicate a CFEB failure. Look for error messages that were generated at
least 5 minutes prior to the failure event by using the following CLI command:
user@host> show log messages | match cfeb
