Description
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.
Indicates the actual state of the port. Determines that electricity flows
between nodes so they can hand-shake. The value is noStateChange,
sleeping, polling, disabled, portConfigurationTrainig, linkup, or
linkErrorRecovery.
Default LinkDown state to return to. The value is noStateChange,
sleeping, or polling. See section 5.5.2, Status Outputs (MAD GET),
InfiniBand Architecture®, Vol. 1, Release 1.1, for more information.
Management key protection bits for the port. The bits are 0, 1, 2, and 3.
See section 14.2.4.1, Levels of Protection, InfiniBand Architecture®, Vol.
1, Release 1.1, for more information.
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. See sections 3.5.10, Addressing, and
4.1.3, Local Identifiers, InfiniBand Architecture®, Vol. 1, Release 1.1, for
more information.
Speed of an active link. The value is 1 (2.5 Gbps).
Maximum speed the link is capable of handling. The value is 0 (No state
change), 1 (2.5 Gbps), or 3 (value derived from link-speed-supported).
Active maximum transmission unit enabled on this port for transmit.
Check the mtu-cap value at both ends of every link and use the lesser
speed. The value is mtu256, mtu512, mtu1024, mtu2048, or mtu4096.
Administrative service level required for this port to send a non-SMP
message to the subnet manager.
Maximum range of data virtual lanes supported by this port. The value is
vl0, vl0ToVl1, vl0ToVl3, vl0ToVl7, or vl0ToVl14. See also oper-VL.
Maximum high-priority limit on the number of bytes allowed for
transmitting high-priority packets when both ends of a link operate with
multiple data virtual-lanes. Used with the virtual-lane arbitration table.
The maximum high-limit is determined by checking the vl-arb-high-cap
on the other side of the link and then negotiating downward.
Highest arbitration value allowed by the arbiter in determining the next
packet in a set of packets to send across the link. Used with the virtual-lane
arbitration table and specified as a VL/Weight pair. See section 14.2.5.9,
VL Arbitration Table, InfiniBand Architecture®, Vol. 1, Release 1.1, for
more information.
