Debugging a Failed Commit

Problem

You are trying to activate a configuration and the commit command continues to fail.

Solution

Watch each step of the commit operation:

Discussion

The previous output shows the results of a successful commit operation. If the configuration contains a mistake, the output indicates where the mistake is:

	[edit]
	aviva@router1# commit | display detail
	2005-02-24 13:46:03 PST: exporting juniper.conf
	2005-02-24 13:46:03 PST: expanding groups
	2005-02-24 13:46:03 PST: finished expanding groups
	2005-02-24 13:46:03 PST: setup foreign files
	2005-02-24 13:46:03 PST: propagating foreign files
	2005-02-24 13:46:03 PST: complete foreign files
	2005-02-24 13:46:03 PST: dropping unchanged foreign files
	2005-02-24 13:46:03 PST: daemons checking new configuration
	[edit protocols rip group alpha-rip-group]
	 'neighbor fe-0/0/0.0'
	 Failed to configure neighbor fe-0/0/0.0: already in group alpha-rip-group
	error: configuration check-out failed

In this example, the error is in the RIP routing protocol, and this error is flagged by the software process (the JUNOS term for a Unix daemon) that checks the configuration.
