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.
