Displaying Configuration Errors

Configuration changes are automatically verified during the commit operation, and a configuration
message is displayed if one or more configuration entries fails. To display the cause of each failure, enter
the show configuration failed commands, as summarized in
Table 2-7
Command
show configuration failed
show configuration failed noerror
Description
(Optional) Assigns a meaningful label. This label is displayed in the
output for the show rollback points [detailed] command instead of the
numeric label.
• The line argument is the text for the optional comment or label.
(Optional) Allows a logical router owner to commit the configuration in
low-memory conditions.
A low-memory warning occurs when a user attempts to commit a target
configuration that exceeds the default capacity of the router.
The recommended resolution to such a warning is to remove
configurations using the no commands.
Caution
Commands to Display Configuration Failure Details
The force option can cause the router to experience severe
problems if low-memory conditions occur. The force option
should be used only to remove configurations.
