This read-write value is the SNMP community string used for SET (write) operations against this device, reads back as undefined, requires subsequent SETs to use the newly written value to be accepted, and resets to the manufacturer default of "private" when the Access Point's reset button is pressed. An admin changes this from its default to restrict who can modify configuration via SNMP, remembering that a factory reset will revert it back to "private". For example, an admin securing the device would change this object away from the well-known default "private" string, understanding a physical reset button press would undo that change.
