LANScan Network Protocol Details

The context sensitive popup menu lets you select the protocol layer to view. Why change layers? You see different information at each layer and it may identify different problems. For example, the Data Link layer identifies the low level, hardware based packet format appearing on the network wire. Seeing multiple types of Data Link protocols may indicate some hardware problems.

By default, LANScan starts with the Session layer. LANScan currently recognizes very few Application layer protocols so not much information is available at that level.

Expand has a special purpose for the Session layer only. Expand displays all protocols by their ID number. In TCP/IP networks, thats the 'Port' number. This is very useful when tracking use of uncommon or custom protocols.
