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
You can specify a .cfg configuration file as a main or backup next-startup configuration file when you use
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:
On an MSR2000 or MSR3000, make sure the specified configuration file is valid and saved to the
root directory of the device's storage medium.
On an MSR4000, make sure the specified configuration file is valid and saved to the root directory
of both the active and standby MPUs' storage media.
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:

configuration file.

By default, no startup configuration

Use the display startup command
and the display

any view to verify the
configuration.
Backing up the main next-startup configuration file
to a TFTP server
Before performing this task, make sure the following requirements are met:
The server is reachable and enabled with TFTP service.
You have read and write permissions.
