UsdNextServerListIndex
Coordinate index value allocation for entries in an associated table, by first reading an index value from this object, then creating an entry, having that index value, in the associated table. The DESCRIPTION clause for an object of this type must identify the associated table. A GET of this object returns the next available index value to be used to create an entry in the associated table; or zero, if no valid index value is available. This object also returns a value of zero when it is the lexicographic successor of a varbind presented in an SNMP GETNEXT or GETBULK request, for which circumstance it is assumed that index allocation is unintended. Successive GETs will typically return different values, thus avoiding collisions among cooperating management clients seeking to create table entries simultaneously. Unless specified otherwise by its MAX-ACCESS and DESCRIPTION clauses, an object of this type is read-only, and a SET of such an object returns a notWritable error.
