<> 144:ef7eb2e8f9f7 28 * This file defines the structure, as seen from the outside, of any Management
<> 144:ef7eb2e8f9f7 29 * Information Base (MIB) implementation. It does not define the contents of the
<> 144:ef7eb2e8f9f7 30 * MIB.
<> 144:ef7eb2e8f9f7 31 *
<> 144:ef7eb2e8f9f7 32 * A MIB is implemented as a map of parameters, each identified by a unique Object ID.
<> 144:ef7eb2e8f9f7 33 * The contents of the map have to be filled in by the actual MIB implementation, by
<> 144:ef7eb2e8f9f7 34 * assigning to the GlobMibMap variable. The mib_param_t data type defines the format
<> 144:ef7eb2e8f9f7 35 * of each parameter in the map. *NOTE:* The length of the last entry in the map must
<> 144:ef7eb2e8f9f7 36 * be 0.
<> 144:ef7eb2e8f9f7 37 *
<> 144:ef7eb2e8f9f7 38 * One parameter must always be present in the MIB map: the system revision. It has
<> 144:ef7eb2e8f9f7 39 * to be set by assigning a value to the systemRevision variable.
<> 144:ef7eb2e8f9f7 40 *
<> 144:ef7eb2e8f9f7 41 * Parameters can be of any data type, and read / write or read only. To resemble
<> 144:ef7eb2e8f9f7 42 * the hierarchical structure of an SNMP MIB, each Object ID consists of four nibbles
<> 144:ef7eb2e8f9f7 43 * (uint16_t) where the more significant nibbles correspond to a higher level in the
<> 144:ef7eb2e8f9f7 44 * hierarchy.
<> 144:ef7eb2e8f9f7 45 *
<> 144:ef7eb2e8f9f7 46 * The contents of the map can be accessed with the fMibSetBytes() and fMibGetBytes()
<> 144:ef7eb2e8f9f7 47 * functions. The implementation of the MIB may also make its parameters accessible
<> 144:ef7eb2e8f9f7 48 * in a more "direct" way; that is left to the implementation. The fMibSetBytes() and
<> 144:ef7eb2e8f9f7 49 * fMibGetBytes() functions are made available to the user interface (see ui.h). In
<> 144:ef7eb2e8f9f7 50 * order to do so, fMibUiInit() must be called during device initialization.
<> 144:ef7eb2e8f9f7 51 *
<> 144:ef7eb2e8f9f7 52 * Additionally, for parameters that have an array as their value, the individual
<> 144:ef7eb2e8f9f7 53 * elements of the array can be accessed using the fMibIndexedSetBytes() and
<> 144:ef7eb2e8f9f7 54 * fMibIndexedGetBytes() functions. The functions are similar to their non-indexed
<> 144:ef7eb2e8f9f7 55 * variants (fMibSetBytes() and fMibGetBytes()), except that they expect the index of
<> 144:ef7eb2e8f9f7 56 * the element as an argument.
<> 144:ef7eb2e8f9f7 57 *
<> 144:ef7eb2e8f9f7 58 * fMibGetBytes() and fMibSetBytes() will normally copy bytes from the MIB parameter
<> 144:ef7eb2e8f9f7 59 * into a given place in memory, or from memory to the MIB parameter. This behaviour
<> 144:ef7eb2e8f9f7 60 * can be overruled by assigning a function to the setAction and / or getAction
<> 144:ef7eb2e8f9f7 61 * fields of the MIB parameter.
<> 144:ef7eb2e8f9f7 62 *
<> 144:ef7eb2e8f9f7 63 * For parameters that have an array as their value, the length field has a slightly
<> 144:ef7eb2e8f9f7 64 * different meaning: the most significant 16 bits contain the length of the array;
<> 144:ef7eb2e8f9f7 65 * the least significant 16 bits contain the width of the array (i.e. the size in
<> 144:ef7eb2e8f9f7 66 * bytes of the array's elements). This implies that the normal fMibGetBytes() and
<> 144:ef7eb2e8f9f7 67 * fMibSetBytes() cannot be used on these parameters; instead, a get and set action
<> 144:ef7eb2e8f9f7 68 * needs to be provided to interpret the length field in case of a non-indexed get
<> 144:ef7eb2e8f9f7 69 * or set.
<> 144:ef7eb2e8f9f7 70 *
<> 144:ef7eb2e8f9f7 71 * To access the MIB fields over the user interface, the module ID must be equal to
<> 144:ef7eb2e8f9f7 72 * MIB_MODULE_ID or 0x01. The data in the packet must have the following structure:
<> 144:ef7eb2e8f9f7 73 * <table>
<> 144:ef7eb2e8f9f7 74 * <tr>
<> 144:ef7eb2e8f9f7 75 * <th>Get (0x00) / Set (0x01) code</th>

<> 144:ef7eb2e8f9f7 103 *
