Saving Configurations
Under normal conditions, configurations you make using the UI are written into cache and
automatically saved into the switch’s flash memory. In this case, it is not necessary to issue a
special command to save your configurations. When you use the UI to enter multiple configu-
rations, periodically the switch will display the following message.
File system compaction in progress . . .
This message indicates that the switch is compacting data in the cache buffer before writing it
into the mpm.cnf file. This message normally disappears after a few seconds.
♦ Warning ♦
It is highly recommended that you use the default
setting and allow the switch’s save function to operate
automatically.
You can change the switch’s save function so that the cache is not saved automatically by
executing the
cacheconfig command. To turn off the switch’s automatic save function, enter
cacheconfig on
at the system prompt. The following message will display.
Cache Configuration is now on
♦ Warning ♦
Any configurations you enter before executing the
saveconfig command will not be saved in case of
system failure or reboot.
Once
cacheconfig is implemented, you must use the saveconfig command to manually
synchronize your configurations into flash memory. When you execute the saveconfig
command at the system prompt, the following message will display.
File system compaction in progress . . .
The UI does not indicate when the cacheconfig function is in operation. However, if you
attempt a reboot the following message will display if you are in the cache configuration
mode.
!!!Warning!!! You are in the cache configuration mode.
Please enter ‘n’/’N’ to the following confirm prompt.
Then enter the UI command “saveconfig”, or
enter the CLI command “dump configuration cache” to
save the current configuration to mpm.cnf in the flash.
Otherwise, all/some your configuration changes will be lost!
Confirm? (n) :
This message gives you the opportunity to execute the saveconfig command prior to the
reboot.
