If a commit operation is successful then all of the candidate changes will take operational
effect and the candidate is cleared. If there is an error in the processing of the commit, or a
'commit confirmed' is not confirmed and an auto-revert occurs, then the router will return to
a configuration state with none of the candidate changes applied. The operator can then
continue editing the candidate and try a commit later.
All commands in the candidate configuration must be in the correct order for a commit to be
successful. Configuration that depends on other candidate objects must be placed after those
objects in the candidate. A set of candidate editing commands (copy, insert, etc) are available
to correct and reorder the candidate configuration.
The edit-cfg mode is primarily intended for building a candidate configuration while
navigating the configure branch of CLI. Many CLI commands in branches other than
configure are supported while in edit-cfg mode, but access to some CLI branches and
command are blocked including the:
The candidate configuration can be saved to a file and subsequently loaded into a candidate
configuration. A saved candidate is similar to, but not the same as an SR OS config file
generated with an admin save command. The saved candidate cannot be used in general as
a configuration file and may not exec without failures.
There is no SNMP access to the candidate configuration and no SNMP management of
candidates although any configuration changes done via a transaction are reported via the
standard SR OS SNMP change traps and basic candidate status information is available via
SNMP.
Failure of a commit may be due to one or more of several reasons including:
Basic System Configuration Guide
• exec command
• enable-admin command
• enable-dynamic-services-config command
• admin branch
• bof branch
• debug branch
• tools branch
• Misordering: The candidate configuration has changes that are not in the correct
order (an object is referred to before it is actually created).
• Invalid options and combinations: Although many syntax errors are eliminated
during the candidate editing process, the candidate configuration may contain
combinations of configuration and options that are not valid and are rejected when
the SR OS attempts to have them take operational effect.
• Out of resources: The application of the candidate may exhaust various system
resources (queues, for example).
