Caution To avoid losing all or part of the configuration stored in NVRAM, always back up the switch
configuration file before upgrading or downgrading the switch software. A software downgrade will
always cause the configuration to be lost. Use the copy config tftp command to back up your
configuration to a TFTP server. Use the copy config flash command to back up the configuration to a
Flash device.
