Table B-17 show ib sm port Command Field Descriptions (continued)

Field	Description
link-width-enabled	Enabled link width. 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 LinkWidthSupported 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.
phy-state	Indicates the actual state of the port. This is used to determine that electricity is flowing between
	nodes and they can hand-shake. The value is noStateChange, sleeping, polling, disabled,
	portConfigurationTraining, linkup, or linkErrorRecovery. The default state upon power-up is polling.
link-down-def-state	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. 2, Release 1.0”, for more
	information.
mkey-prot-bits	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 1.0”, for more information.
lmc	Local identifier mask control (LMC) for multipath support. An 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 1.0”, for more information.
link-speed-active	Speed of an active link. The value is 1 (2.5 Gbps).
link-speed-enabled	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).
neighbor-mtu	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.
master-sm-SL	Administrative service level required for this port to send a non-SMP message to the subnet manager.
VL-cap	Maximum range of data virtual lanes supported by this port. The value is vl0, vl0ToVl1, vl0ToVl3,
	vl0ToVl7, or vl0ToVl14. See also oper-VL.
VL-high-limit	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.
