Port Statistics Field Descriptions

Link State:

Indicates whether the InfiniBand link associated with the physical port is up or down. Possible values are no state change, down, init, armed, active, and unknown.

Physical State:

Indicates whether the internal connection to the InfiniBand port is up or down. Possible values are No State Change, Sleep, Polling, Disabled, Training, Up, and Error Recovery.

Link Down Default:

Indicates the default down state as set by the Fabric Manager. Possible values are No State Change, Sleep, Polling, and Unknown.

Active Link Width:

Indicates the number of full duplex serial links that are currently being used on a port. The current bandwidth capability of a port is determined by multiplying this value by the Active Link Speed of this port. For instance a 4X DDR link has a bandwidth capability of 20Gb/s.

NOTE:Values of 1X are possible in this field with 4X IB cables if poor cable connections or defective 4X IB cables are used.

Link Width Enabled:

Link Width Enabled is the allowed link width(s) that a port can arbitrate to. Normally, this defaults to the Link Width Supported value, but can be overridden by the subnet manager.

Link Width Supported:

Indicates the link width in terms of multipliers of 2.5 Gbit/sec full duplex serial links supported by the port.

Active Link Speed:

Indicates the speed of the full duplex serial link. This is either 2.5Gbps (single data rate, or SDR), or 5.0Gbps (double data rate, or DDR).

Link Speed Enabled:

Link Speed Enabled is the allowed link speed(s) that a port can arbitrate to. Normally this defaults to the Link Speed Supported value, but can be overridden by the subnet manager.

Link Speed Supported:

The supported link speed of the port. This could be 2.5Gbps (SDR), 5.0Gbps (DDR) or both.
