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).
Corresponds to external leaf module number/port number, spine module number/port number, and
all interswtich links.
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.
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.
Indicates the default down state as set by the subnet manager. Possible values are No State Change,
Sleep, Polling, and Unknown.
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.
Values of 1X are possible in this field with 4X IB cables if poor cable connections or defective
4X IB cables are used.
Indicates actual link width as opposed to the supported link width.
Indicates the link width in terms of multipliers of 2.5 Gbit/sec full duplex serial links supported by
the port.
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).
Indicates the actual link speed as opposed to the supported link speed. This could be 2.5Gbps (SDR),
5.0Gbps (DDR) or both.
The supported link speed of the port. This could be 2.5Gbps (SDR), 5.0Gbps (DDR) or both.
The number of 32-bit data words transmitted by the port, not including flow control and VCRC data.
