A LMC resides on 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 allows one LID on the port. For more information, see sections 3.5.10, "Addressing" and 4.1.3, "Local Identifiers" in InfiniBand Architecture®, Vol. 1, Release 1.1. Speed of an active link. The field displays 2.5 Gbps. Maximum speed that the link can handle. The value can be 0 (no state change), 1 (2.5 Gbps), or 3 (value derived from LinkSpeedSupported). Active maximum transmission unit (MTU) enabled on this port for transmission. The subnet manager is responsible for checking the MTUCap on both ends of a link and setting the neighbor-MTU on both sides appropriately. The value appears as 256, 512, 1024, 2048, or 4096. Administrative service level required for this port to send a non-SMP message to the subnet manager. Maximum range of data virtual lanes (VLs) supported by this port. 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 v1-arbitration-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 transmit across the link. Used with the virtual-lane arbitration table and specified as a VL/Weight pair. For more information, see section 14.2.5.9, "VL Arbitration Table" of InfiniBand Architecture®, Vol. 1, Release 1.1. Lowest arbitration value allowed by the arbiter in determining the next packet in a set of packets to transmit across the link. Used with the virtual-lane arbitration table and specified as a VL/Weight pair. For more information, see section 14.2.5.9, "VL Arbitration Table" of InfiniBand Architecture®, Vol. 1, Release 1.1. Determines, with neighbor-mtu, the maximum transmission size supported on this port. The lesser of MTUCap and NeighborMTU determines the actual MTU used. The value appears as 256, 512, 1024, 2048, or 4096. Number of sequentially dropped packets at which the port enters a VLStalled state. For more information, see section 18.2.5.4, "Transmitter Queuing" in InfiniBand Architecture®, Vol. 1, Release 1.1. Maximum duration allowed to packets at the head of a virtual-lane queue. Used with VLStallCount to determine the outgoing packets to discard. Administrative limit for the number of virtual lanes allowed to the link. Do not set this above the VLCap value. Boolean value that indicated whether or not to support optional partition enforcement for the packets that were received by this port. 6-142 Cisco SFS 7000 Series Product Family Command Reference Guide OL-9163-02
