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:
In standalone mode, make sure the specified configuration file is valid and saved to the root
•
directory of both the active and standby MPUs' storage media.
In IRF mode, make sure the specified configuration file is valid and saved to the root directory of all
•
MPUs' storage media in the IRF fabric.
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:
Task
Specify the next-startup
configuration file.
Backing up the main next-startup configuration file
to a TFTP server
Before performing this task, make sure the server is reachable and enabled with TFTP service, and you
have read and write permissions.
To back up the main next-startup configuration file to a TFTP server:
Command
startup saved-configuration cfgfile
[ backup | main ]

Remarks
Use the display startup command
and the display
saved-configuration command in
any view to verify the
configuration.
