pressing Enter, the AMB and SMB will automatically save the current configuration to the
specified configuration file, and use the file as the configuration file for the next startup, thus
keeping the consistency of the configuration files on the AMB and SMB.
z If the configuration file auto-save function is not enabled, when you save the current configuration
by executing the save [ safely ] command or executing the save filename all command and then
pressing Enter, only the AMB will automatically save the current configuration to the specified
configuration file, and use the file as the configuration file for the next startup; the SMB will neither
save the configuration file nor configure the file for the next startup.
2) Distributed IRF device
z After the configuration file auto-save function is enabled, when you save the current configuration
by executing the save [ safely ] command or executing the save filename all command and then
pressing Enter, each main board of a IRF will automatically save the current configuration to the
specified configuration file, and use the file as the configuration file for its next startup, thus
keeping the consistency of the configuration files on the AMB and SMBs of the IRF.
z If the configuration file auto-save function is not enabled, when you save the current configuration
by executing the save [ safely ] command or executing the save filename all command and then
pressing Enter, only the AMB of the IRF will automatically save the current configuration to the
specified configuration file, and use the file as the configuration file for the next startup; the SMBs
of the IRF will neither save the configuration file nor reconfigure the file for the next startup.
Follow these steps to configure the configuration file auto-save function:
To do… Use the command… Remarks
Enter system view system-view —
Enable configuration file auto-save slave auto-update config
Optional
Enabled by default.
If you execute the save filename command and press Enter, the system saves the current
configuration to the specified path, but the SMB does not save the configuration.
Modes in Saving the Configuration
z Fast saving mode. This is the mode when you use the save command without the safely keyword.
The mode saves the file more quickly but is likely to lose the existing configuration file if the device
reboots or the power fails during the process.
z Safe mode. This is the mode when you use the save command with the safely keyword. The
mode saves the file more slowly but can retain the configuration file in the device even if the
device reboots or the power fails during the process.
