Note Spine chips are referenced by the spine number and the switch chip identifier. Each spine module contains two switch chips (Switch chip A and B).

Port Statistics Field Descriptions

Port Name/Port Number:

Corresponds to external leaf module number/port number, spine module number/port number, and all interswtich links.

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 subnet manager. Possible values are No State Change, Sleep, Polling, and Unknown.

Active Link Width:

Indicates the bandwidth of the link on the backplane. The bandwidth is specified as a multiplier of 2.5 Gbit/sec full duplex serial links. As an example, 4X specifies a bandwidth of 10 Gbit/sec.

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:

Indicates actual link width as opposed to the supported link width.

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:

Indicates the actual link speed as opposed to the supported link speed. This could be 2.5Gbps (SDR), 5.0Gbps (DDR) or both.

Link Speed supported:

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

InfiniBand Statistics:

Transmit 32 Bit Words:

The number of 32-bit data words transmitted by the port, not including flow control and VCRC data.
