The configuration rollback function 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 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: • Make sure the specified configuration file is valid and saved to the root directory of each member device's storage medium. • 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 a next-startup configuration file. Command Remarks startup saved-configuration cfgfile [ backup | main ] Use the display startup command and the display saved-configuration command in any view to verify the configuration. 88
