What is cmTopologyItemDescr?
This DisplayString (up to 128 characters) holds a description of a topology item. An admin sets this to record extra detail about a specific network element beyond its short ID. For example, an operator would set cmTopologyItemDescr to note a device's role, such as 'aggregation switch for floor 3', to aid anyone reviewing the topology later.
