The configuration rollback feature might fail to reconfigure some commands in the running
configuration for one of the following reasons:
•
A command cannot be undone because prefixing the undo keyword to the command does not
result in a valid undo command. For example, if the undo form designed for the A [ B ] C
command is undo A C , the configuration rollback feature cannot undo the A B C command.
This is because the system does not recognize the undo A B C command.
•
A command (for example, a hardware-dependent command) cannot be deleted, overwritten, or
undone due to system restrictions.
•
The commands in different views are dependent on each other.
•
Commands or command settings that the device does not support cannot be added to the
running configuration.
Configuring configuration commit delay
This feature enables the system to automatically remove the settings you made during a
configuration commit delay interval if you have not manually committed them.
You specify the configuration commit delay interval by using the configuration commit delay timer.
Any settings made during the delay interval will be automatically removed if you have not manually
committed them before the timer expires.
This feature prevents a misconfiguration from causing the inability to access the device and is
especially useful when you configure the device remotely.
When you use this feature, follow these restrictions and guidelines:
•
In a multi-user context, make sure no one else is configuring the device.
•
You cannot perform any operations during the configuration rollback.
•
The configuration commit delay feature is a one-time setting. The feature is disabled when the
commit delay timer expires or after a manual commit is performed.
•
You can reconfigure the configuration commit delay timer before it expires to shorten or extend
the commit delay interval. The settings made during the delay interval will be removed if you
have not committed them before the new timer expires.
To configure the configuration commit delay feature:
Step Command
1. Enter system view.
system-view
2. Start the commit delay timer.
configuration commit delay delay-time
3. (Optional.) Commit the settings configured
after the commit delay timer started.
configuration commit
Specifying a next-startup configuration file
CAUTION:
Using the undo startup saved-configuration command can cause an IRF split after the IRF fabric
or an IRF member reboots. When you execute this command, make sure you understand its impact
on your network.
You can specify a .cfg file as a next-startup configuration file when you execute the save [ safely ]
[ backup | main ] [ force ] command.
