• 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.
