Step 2: Check the System Uptime

Action

To check the system uptime, use the following CLI command:

user@host> show system uptime

Sample Output

user@host> show system uptime

Current time:      2002-07-17 16:43:45 PDT

What It Means

The command output displays the time when the system was last booted, in days and hours. If the boot time is short, it can indicate a Routing Engine or 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
