Saving Configurations

Page 9-33

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.
