Display a Route Through the Fabric

Often you need to know the route between two nodes. The ibtracert command can provide that information by displaying the GUIDs, ports, and LIDs of the nodes along the route.

• On the management controller, type.

  FabMan@switch_name->ibtracert slid dlid

  where:

  • slid is the LID of the source node.

  • dlid is the LID of the destination node.

  For example:

  FabMan@switch_name->ibtracert 15 14
  From switch {0x00212856cd22c0a0} portnum 0 lid 15-15 "SUN IB QDR GW switch mnm34-97"
  [1] -> ca port {0x00212856cd22c042}[2] lid 14-14 "SUN IB QDR GW switch mnm34-97 Bridge 1"
  To ca {0x00212856cd22c040} portnum 2 lid 14-14 "SUN IB QDR GW switch mnm34-97 Bridge 1"
  FabMan@switch_name->

  Note - The output for your InfiniBand fabric will differ from that in the example.

  For this example:

  • The route starts at the switch with GUID 0x00212856cd22c0a0 and is using port 0. The switch is LID 15 and in the description, the switch host's name is mnm34-97.

  • The route enters at port 1 of the CA with GUID 0x00212856cd22c042 and exits at port 2. The CA is LID 14 and is within bridge chip 1.
