Port Statistics Field Descriptions - Intel True Scale Fabric 12000 Series User Manual

L = Leaf module number
A = Spine module switch chip A
B = Spine module switch chip B
Example: S113AP13L225P24 is the ISL between spine module 113, switch chip
A, port 13 and leaf module 225, port 24.
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

Link State:
Indicates whether the IB 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 IB 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), or 10.0Gbps (quad data rate, or
QDR).
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.
