    Like most networking devices, Cabletron’s devices draw their functionality from a collection of proprietary MIBs and IETF RFCs. In addition, Cabletron’s newer intelligent devices – like the MicroMMAC-T – organize their MIB data into a series of “components.” A MIB component is a logical grouping of MIB data, and each group controls a defined set of objects.
