z
The saving and rollback operations are executed only on the AMB. To make the configuration
rollback take effect on the new AMB after an active/standby switchover, execute the archive
configuration location command to specify the path and filename prefix of the saved
configuration file on both the AMB and SMB. Therefore, before the execution of this command,
ensure that the specified path is available on both the AMB and SMB, and the path cannot include
any slot number. (distributed device)
z
The saving and rollback operations are executed only on the AMB of a IRF. To make the
configuration rollback take effect on the new AMB after an AMB change, execute the archive
configuration location command to specify the path and filename prefix of the saved
configuration file on all the main boards of the IRF. Therefore, before the execution of this
command, ensure that the specified path is available on all the main boards of the IRF, and the
path cannot include any member ID and slot number. (distributed IRF device)
z
If the undo archive configuration location command is executed, the current running
configuration can neither be saved manually nor automatically, and the configuration by executing
the archive configuration interval and archive configuration max commands restores to the
default, meanwhile, the saved configuration files are cleared.
z
The value of the file-number argument is determined by the memory space. You are recommended
to set a comparatively small value for the file-number argument if the available memory space is
small.
Saving the Current Running Configuration Automatically
You can configure the system to save the current running configuration at a specified interval, and use
the display archive configuration command to view the filenames and save time of the saved
configuration files, so as to roll back the current configuration to a previous configuration state.
Configure an automatic saving interval according to the storage medium performance and the
frequency of configuration modification:
z
If the configuration of the device does not change frequently, you are recommended to save the
current running configuration manually as needed
z
If a low-speed storage medium (such as a flash) is used, you are recommended either to save the
current running configuration manually, or to configure automatic saving with an interval longer
than 1,440 minutes (24 hours).
z
If a high-speed storage medium (such as a CF card) is used and the configuration of the device
changes frequently, you are recommended to set a shorter saving interval.
Follow these steps to automatically save the current running configuration:
