7.3.1.3 Addressing
The following addressing modes can be used to define the IB ports:
• Using a Directed Route to the destination: (Tool option ‘-d’)
This option defines a directed route of output port numbers from the local port to the destination.
• Using port LIDs: (Tool option ‘-l’):
In this mode, the source and destination ports are defined by means of their LIDs. If the fabric is con-
figured to allow multiple LIDs per port, then using any of them is valid for defining a port.
• 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.
This section applies to the ibdiagpath tool only. A tool command may
require defining the destination device or port to which it applies.
