Provides desired (and actual) state of the given module. Notice that not all values may be supported by a specified physical module. In this case an SNMP error returned when a set is attempted.

All modules (even empty slots) are in an unknown(1) state when the chassis first powers up.

The invalid state is for non-existant modules, and hence is never seen. Neither of the unknown(1) or invalid(2) status values can be written.

A physical module can be activated by writing a value of enable(3).

A physical module may be de-activated by writing a value of disable(4). In a disabled state, the module is present in the chassis, but is benign. A disabled module is availible for subsequent activation.

Writing a value of reset(5), disables the module AND initiates a reset sequence.

Writing a value of load(6), disables the module AND initiates a software load sequence.

Writing a value of test(7), disables the module AND initiates selftest within the module.
