Follow these steps to save the current configuration (distributed IRF device):
To do… Use the command… Remarks
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 Enabling Configuration
File Auto-Save . (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 Enabling Configuration
File Auto-Save . (distributed IRF device)
z During the execution of the save 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 Specifying a Startup Configuration File for
the Next System Startup ).
Setting Configuration Rollback
Introduction
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:
