D000101-000 E 1-45
P = Leaf module port number
Example: L101P01 is leaf module 101 port number 1.
Interswitch Link (ISL) Ports:
S = Spine module number
L = Leaf 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.
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:
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).
NOTE:
Values of 1X are possible in this field with 4X IB cables if poor cable
connections or defective 4X IB cables are used.
