Description: This value is used as the first index into the table. The shelf.board portions of the PII value are used to specify a particular SCM that will be the source of the connection.

What is cmTrunkTopoSrc?

This read-only CmObjectPII is the first table index, giving the shelf.board PII of the SCM that originates a given inter-shelf topology path. An admin uses it to identify which card starts a particular routing path when tracing connectivity across shelves. For example, an admin sees cmTrunkTopoSrc=2.1 confirming shelf 2 board 1 is the starting point of the topology path currently being diagnosed.

Examples
