Field

Description

Link Width Enabled

Enabled link width (bandwidth). The value is an integer that

 

indicates the enabled link-width sets for this port. The value

 

may be:

 

• 0 (no state change)

 

1 (1x)

 

2 (4x)

 

• 3 (1x or 4x)

 

8 (12x)

 

• 9 (1x or 12x)

 

• 10 (4x or 12x)

 

• 11 (1x, 4x or 12x)

 

• 255 (set this parameter to the link-width-supported value)

 

 

Link Width Supported

Supported link width. The value is 1 (1x), 3 (1x or 4x), or 11

 

(1x, 4x, or 12x).

 

 

Link Width Active

Active link width. Used in conjunction with LinkSpeedActive

 

to determine the link rate between two nodes. The value is 1

 

(1x), 2 (4x), or 8 (12x).

 

 

Link Speed Supported

Supported link speed. The value is 1 (2.5 Gbps).

 

 

State

A higher form of addressing than PhyState, State determines

 

that the nodes can actually communicate and indicates the state

 

transition that has occurred. A transition is a port change from

 

down to initialize, initialize to down, armed to down, or active

 

to down as a result of link state machine logic. Changes to the

 

port state resulting from SubnSet have no affect on this

 

parameter value. The value is noStateChange, down, initialize,

 

armed, or active.

 

 

Physical State

Indicates the physical state of the port. This is used to determine

 

that electricity is flowing between nodes and they can perform a

 

handshake. The value is noStateChange, sleeping, polling,

 

disabled, portConfigurationTraining, linkup, or

 

linkErrorRecovery. The default state upon powerup is polling.

 

 

Link Down Def State

Default LinkDown state to return to. The value is

 

noStateChange, sleeping, or polling. Refer to section 5.5.2,

 

Status Outputs (MAD GET), “InfiniBand® Architecture, Vol. 2,

 

Release 1.0”, for more information.

 

 

MKey Protocol Bits

Management key protection bits for the port. The bits are 0, 1, 2,

 

and 3. Refer to section 14.2.4.1, Levels of Protection,

 

“InfiniBand® Architecture, Vol. 1, Release 1.0”, for more

 

information.

 

 

LMC

Local-identifier mask control (LMC) for multipath support. A

 

LMC is assigned to each channel adapter and router port on the

 

subnet. It provides multiple virtual ports within a single physical

 

port. The value of the LMC specifies the number of path bits in

 

the LID. A value of 0 (zero) indicates one LID is allowed on this

 

port. Refer to sections 3.5.10, Addressing, and 4.1.3, Local

 

Identifiers, “InfiniBand® Architecture, Vol. 1, Release 1.0”, for

 

more information.
