Setting Configuration Rollback - 3Com S7906E Configuration Manual

Follow these steps to save the current configuration (distributed IRF device):
To do...
Save the current configuration
to the specified file, but the
configuration file will not be set
as the file for the next startup
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
The configuration file must be with extension .cfg.
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
File Auto-Save. (distributed device)
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
File Auto-Save. (distributed IRF device)
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
for the Next System

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:
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.
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:
Use the command...
save file-url [ all | chassis
chassis-number slot
