5. If you want to run the prior software version, K.12.43 in this example,
enter this command:
HP Switch(config)# boot system flash secondary config
configK1243.cfg
After rebooting, the switch is running software version K.12.43 and is
using the configuration file that you saved for this software version,
configK1243.cfg.
You can also save the K.12.43 configuration file on a TFTP server. If you wanted
to reload the K.12.43 version of the software again, reload the configuration
file before you do the reload.
HP Switch(config)# show flash
