Follow these steps to save the current configuration (distributed IRF device): 

Save the current configuration 
to the specified file, but the 
configuration file will not be set 
as the file for the next startup 

save file-url [ all | chassis 
chassis-number slot 
slot-number ] 

Save the current configuration 
to the root directory of the 
storage medium of each main 
boards of a IRF and specify the 
file as the startup configuration 
file that will be used at the next 
system startup 

save [ safely ] 

Required 

Use either command 

Available in any view. 

 

z 

The configuration file must be with extension .cfg. 

z 

Whether the save [ safely ] command or the save filename all command+Enter takes effect on 

both the AMB and SMB or on the AMB only depends on whether the configuration file auto-save 

function is enabled. For the configuration file auto-save function, refer to 

. (distributed device) 

z 

Whether the save [ safely ] command or the save filename all command+Enter takes effect on all 

the main boards or on the AMB of a IRF depends on whether the configuration file auto-save 

function is enabled. For the configuration file auto-save function, refer to 

. (distributed IRF device) 

z 

During the execution of the save [ safely ] command, the startup configuration file to be used at the 

next system startup may be lost if the device reboots or the power supply fails. In this case, the 

device will boot with the null configuration, and after the device reboots, you need to re-specify a 

startup configuration file for the next system startup (refer to 

). 

 

Configuration rollback allows you to revert to a previous configuration state based on a specified 

configuration file. The specified configuration file must be a valid .cfg file, namely, it can be generated 

by using either the backup function (manually or automatically) or the save command, and even the 

compatible configuration file of another device. You are recommended to use the configuration file that 

is generated by using the backup function (manually or automatically). Configuration rollback is applied 

in the following situations:  

z 

The current configurations are wrong; and there are too many wrong configurations to locate or to 

correct one by one. Rolling back the current configuration to a correct one is needed. 

z 

The application environment has changed and the device has to run in a configuration state based 

on a previous configuration file without being rebooted. 

Set configuration rollback following these steps:
