cisco Flash Device Programming Jumper

1.3.6.1.4.1.9.9.10.1.1.2.1.11

This object gives the state of a jumper (if present and can be determined) that controls the programming voltage called Vpp to the Flash device. Vpp is required for programming (erasing and writing) Flash. For certain older technology chips it is also required for identifying the chips (which in turn is required to identify which programming algorithms to use; different chips require different algorithms and commands). The purpose of the jumper, on systems where it is available, is to write protect a Flash device. On most of the newer remote access routers, this jumper is unavailable since users are not expected to visit remote sites just to install and remove the jumpers when upgrading software in the Flash device. The unknown(3) value will be returned for such systems and can be interpreted to mean that a programming jumper is not present or not required on those systems. On systems where the programming jumper state can be read back via a hardware register, the installed(1) or notInstalled(2) value will be returned. This object is expected to be used in conjunction with the ciscoFlashPartitionStatus object whenever that object has the readOnly(1) value. In such a case, this object will indicate whether the programming jumper is a possible reason for the readOnly state.
