Display the Link Status of a Node

If you want to know the link status of a node in the InfiniBand fabric, the ibportstate command can tell you the state, width, and speed of that node.

• On the management controller, type.

  FabMan@switch_name->ibportstate lid port

  where:

  • lid is the LID of the node.

  • port is the port of the node.

  For example:

  FabMan@switch_name->ibportstate 1 22
  PortInfo:
  # Port info: Lid 1 port 22
  LinkState:.......................Active
  PhysLinkState:...................LinkUp
  LinkWidthSupported:..............1X or 4X
  LinkWidthEnabled:................1X or 4X
  LinkWidthActive:.................4X
  LinkSpeedSupported:..............2.5 Gbps or 5.0 Gbps or 10.0 Gbps
  LinkSpeedEnabled:................2.5 Gbps or 5.0 Gbps or 10.0 Gbps
  LinkSpeedActive:.................10.0 Gbps
  Peer PortInfo:
  # Port info: Lid 1 DR path slid 65535; dlid 65535; 0,22 port 8
  LinkState:.......................Active
  PhysLinkState:...................LinkUp
  LinkWidthSupported:..............1X or 4X
  LinkWidthEnabled:................1X or 4X
  LinkWidthActive:.................4X
  LinkSpeedSupported:..............2.5 Gbps or 5.0 Gbps or 10.0 Gbps
  LinkSpeedEnabled:................2.5 Gbps or 5.0 Gbps or 10.0 Gbps
  LinkSpeedActive:.................10.0 Gbps
  FabMan@switch_name->

  In the output, the Active parameters are the current state of the port.
