What is nlMatrixTopNProtocolDirLocalIndex?

This number identifies which network-layer protocol (e.g., IP, IPX, AppleTalk) the source and destination addresses in this top-N entry belong to. Engineers use this to distinguish IPv4 conversations from IPv6 or other protocol families sharing the same monitoring table. Example: value 4 might mean IPv4, allowing the engineer to filter top talkers by protocol type.
