Does not conform as cleanly to the manager/agent paradigm of CMIP and SNMP. Agents are contained within device and are semi-managed by an element manager, which must be managed by a higher level management system with decision making capabilities.

ASCII based. Flat, relational, functional.
Standard “de jour” - changes from release to release and creates dependence on element managers from vendors.
