is undo A C, the configuration rollback function cannot undo the A B C command, 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.

Specifying a next-startup configuration file

CAUTION:
In an IRF fabric, use the undo startup saved-configuration command with caution. This command can
cause an IRF split after the IRF fabric or an IRF member reboots.
You can specify a .cfg configuration file as a main or backup next-startup configuration file when using
the save [ safely ] [ backup | main ] [ force ] command to save the running configuration.
Alternatively, you can execute the startup saved-configuration cfgfile [ backup | main ] command to
specify a configuration file as the main or backup next-startup configuration file. When performing this
task, follow these guidelines:
Configuration files stored in a USB disk cannot be specified as the next-startup configuration file.
•
Make sure the specified configuration file is valid and saved to the root directory of each member
•
device's flash memory.
• If neither backup nor main is specified, this command sets the configuration file as the main
next-startup configuration file.
Even though the main and backup next-startup configuration files can be the same one, specify
•
them as separate files for high availability.
The undo startup saved-configuration command changes the attribute of the main or backup
•
next-startup configuration file to NULL instead of deleting the file.
To specify a next-startup configuration file, perform the following task in user view:
