You can restore an old configuration file stored in the flash directory that was 
generated with the

system snapshot

command.

To activate a configuration file, use the

flash config 

command.

The restored configuration file will only be activated when the switch is next 

rebooted.

After activating a new configuration file and performing a reset to the 

module, the module takes longer than usual to boot because it is using the new 
values.  Because of this, when activating a configuration file that has switch-wide 
parameters (such as the ATM prefix or IP address) different from the current RAM 
settings, the module needs to be alone in the switch.  If there are other modules in 
the switch, the module using the new config file will take longer to boot up, and 
another module in the switch will become the Master Agent and use the old switch-
wide settings.

When the module reboots using the new configuration file, the current LANE 
configuration is saved in the file config.bak. If you need to restore the previous 
LANE configuration, you need to perform the following steps.
1.

Delete the file config.data using the 

flash delete

 command.

2.

Rename the file config.bak to config.data using the 

flash rename

 command.

3.

Reset the module using the <- -> reset pushbuttons on the module front panel.

To deactivate an active configuration file, use the

flash config 

disable

command.

Command:

M15-155s8:/>flash config <filename>

Example

M15-155s8:/>flash config new_cfile

Parameters: 

<filename>

The name of the configuration file that you wish to 
activate

Command:

M15-155s8:/>flash config disable

Output:

No configuration file is currently active.
