About Airespace Switch and Appliance MemoryAirespace Switch and Appliance Memory
The Airespace Wireless Switches and WLAN Appliances contain two kinds of memory: volatile RAM,
which holds the current, active Airespace Switch or Appliance configuration, and NVRAM (non-volatile
RAM), which holds the reboot configuration. When you are configuring the AireOS in an Airespace
Switch or Appliance, you are modifying volatile RAM; you must save the configuration from the volatile
RAM to the NVRAM to ensure that the Airespace Switch or Appliance reboots in the current
configuration.
Knowing which memory you are modifying is important when you are:
• Using the Startup Wizard
• Clearing Configurations
• Saving Configurations
• Resetting the Airespace Switch or Appliance
• Logging Out of the CLI
