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