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-activ
e
Speed of an active link. The value is 1 (2.5 Gbps).
link-speed-enabl
ed
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.
VL-arb-high-cap 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 1.0”, for more information.
VL-arb-low-cap Lowest 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 1.0”, for more information.
mtu-cap Used in conjunction with neighbor-mtu to determine the maximum transmission size supported on this
port. The lesser of mtu-cap and neighbor-mtu determines the actual MTU used. The value is 256, 512,
1024, 2048, or 4096
VL-stall-count Number of sequentially dropped packets at which the port enters a VLStalled state. The virtual lane exits
the VLStalled state (8 * HLL) units after entering it. See section 18.2.5.4, Transmitter Queuing,
“InfiniBand™ Architecture, Vol. 1, Release 1.0”, for a description of HLL.
HOQ-life Maximum duration allowed to packets at the head of a virtual-lane queue. Used with VL-stall-count to
determine the outgoing packets to discard.
oper-VL Administrative limit for the number of virtual lanes allowed to the link. Do not set this above the VL-cap
value. The value is vl0, vl0-Vl1, vl0-Vl3, vl0-Vl7, or vl0-Vl14.
in-part-enforce Boolean value that indicates whether or not to support optional partition enforcement for the packets
received by this port. There is no default value.
out-part-enforce Boolean value that indicates whether or not to support optional partition enforcement for the packets
transmitted by this port. There is no default value.
in-filter-raw-pkt
-enforce
Boolean value that indicates whether or not to support optional raw packet enforcement for the raw
packets received by this port. There is no default value.
