8.3.9.3 Topology File Format
The topology file format is largely intuitive. Most identifiers are given textual names like vendor
ID (vendid), device ID (device ID), GUIDs of various types (sysimgguid, caguid, switchguid,
etc.). PortGUIDs are shown in parentheses (). For switches, this is shown on the switchguid line.
For CA and router ports, it is shown on the connectivity lines. The IB node is identified followed
by the number of ports and the node GUID. On the right of this line is a comment (#) followed by
the NodeDescription in quotes. If the node is a switch, this line also contains whether switch port
0 is base or enhanced, and the LID and LMC of port 0. Subsequent lines pertaining to this node
show the connectivity. On the left is the port number of the current node. On the right is the peer-
node (node at other end of link). It is identified in quotes with nodetype followed by - followed
by NodeGUID with the port number in square brackets. Further on the right is a comment (#).
What follows the comment is dependent on the node type. If it is a switch node, it is followed by
the NodeDescription in quotes and the LID of the peer node. If it is a CA or router node, it is fol-
lowed by the local LID and LMC and then followed by the NodeDescription in quotes and the
LID of the peer node. The active link width and speed are then appended to the end of this output
line.
Example
Non-Chassis Nodes
When grouping is used, InfiniBand nodes are organized into chasses which are numbered. Nodes
which cannot be determined to be in a chassis are displayed as "Non-Chassis Nodes". External
ports are also shown on the connectivity lines.
