• Using port names defined in the topology file: (Tool option ‘-n’)
This option refers to the source and destination ports by the names defined in the topology file.
(Therefore, this option is relevant only if a topology file is specified to the tool.) In this mode, the tool
uses the names to extract the port LIDs from the matched topology, then the tool operates as in the ‘-l’
option.
