To carry out a controlled shutdown of the module in preparation for a power down, use
the
system halt
command.
Taking a snapshot of the current system configuration
You can take a snapshot of the current system configuration of your module to produce
a backup configuration file or before you carry out a system upgrade. This file is saved
into the flash directory of the switch.
To take a snapshot of the current system configuration of the switch, use the
system
snapshot
command.
To re-activate the configuration file later, use the
flash config
command.
Note: The snapshot command saves all the module’s parameters in the same file
(system wide, module specific, LANE etc).
LANE parameters only, are automatically saved in the text file config.data. This file may
also be uploaded and downloaded and can be used to copy a LANE configuration from
one module to another (in the same or another switch). After you have downloaded a
new config.data file you need to reset the module manually using the <- -> reset
pushbuttons on the module front panel in order for the information in the new
config.data file to take effect (do not use the CLI
reboot
command because this will
change the config.data file with its current RAM data). During the power-up process the
module will use the information stored in the new config.data file.
