Table
Field | Description | |
Link Width Enabled | Enabled link width (bandwidth). The value is an integer that | |
| indicates the enabled | |
| 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 | 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 | ||
| 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. |
