• On the 6604/6608/6616 router, do not remove or install a card while the system is executing the
configuration replace file command.
• Make sure the replacement configuration file is created by using the configuration archive function
or the save command on the current device.
• If the configuration file is not created on the current device, make sure the configuration file content
format is fully compatible with the current device.
• The replacement configuration file is not encrypted.
To perform configuration rollback:

Command
1. Enter system view.

2. Perform configuration rollback.
configuration replace file filename
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 configuration file for the next startup
You can specify a .cfg configuration file as the main startup configuration file to be used at the next
startup when you use the save command to save the running configuration to it.
Alternatively, perform the following task in user view to specify a next-startup configuration file:
Task Command Remarks
Specify a next-startup
configuration file.
startup saved-configuration
cfgfile [ backup | main ]
On the 6604/6608/6616 router, the setting
applies to both active MPU and standby MPU.
IMPORTANT:
The configuration file must use the .cfg extension and
be saved in the root directory of a storage medium.
Backing up the next-startup configuration file to a
TFTP server
Before performing this task, make sure the following requirements are met:
