This configuration value sets how many buffers of size class 6 the STREAMS subsystem's buffer cache is configured to hold for the STREAMS I/O subsystem on this host. The source MIB's own DESCRIPTION for this object is only the placeholder text "T B S" (to be supplied), so this reading is inferred from the object's name, its position in the STREAMS admin table (whose table-level DESCRIPTION says it holds "configuration information for a STREAMS subsystem"), and its Integer32 syntax; it corresponds to the live in-use/used/max-used/fails counters kept for the same size class 6 in the companion statistics table (e.g. streamsStatsBufs6Config).
