Table 5-9:Topology Port Properties Window Fields

Field	Description
Subnet Prefix	64-bit value that identifies the IB subnet to which this port
	belongs.
Node GUID	64-bit GUID of the node to which this port belongs.
Port	Port number (integer) on the node (host).
MKey	64-bit management key for this port. Refer to section 14.2.4,
	Management Key and 3.5.3, Keys, “InfiniBand® Architecture,
	Vol. 1, Release 1.0”, for more information.
GID Prefix	64-bit GID prefix for this port. This prefix is assigned by the
	SM, based upon the port router and the rules for local identifiers.
	Refer to section 4.1.3, Local Identifiers, “InfiniBand®
	Architecture, Vol. 1, Release 1.0”, for more information.
LID	16-bit base-LID of this port.
Master SM LID	16-bit base LID of the master SM managing this port.
Cap Mask	The capability mask identifies the functions that the host
	supports. 32-bit bitmask that specifies the supported capabilities
	of the port. A bit value of 1 (one) indicates a supported
	capability. The bits are 0, 11-15, 18, 21-31 (Reserved and
	always 0.), 1 IsSM, 2 IsNoticeSupported, 3 IsTrapSupported, 4
	IsResetSupported, 5 IsAutomaticMigrationSupported, 6
	IsSLMappingSupported, 7 IsMKeyNVRAM (supports M_Key
	in NVRAM), 8 IsPKeyNVRAM (supports P_Key in NVRAM),
	9 Is LED Info Supported, 10 IsSMdisabled, 16
	IsConnectionManagementSupported, 17
	IsSNMPTunnelingSupported, 19
	IsDeviceManagementSupported, 20
	IsVendorClassSupported.Values are expressed in hexadecimal.
Diag Code	16-bit diagnostic code. Refer to section 14.2.5.6.1 Interpretation
	of Diagcode, “InfiniBand® Architecture, Vol. 1, Release 1.0”,
	for more information. This field does not currently apply to your
	device.
MKey Lease Period	Initial value of the lease-period timer in seconds. The lease
	period is the length of time that the M_Key protection bits are to
	remain non-zero after a SubnSet (PortInfo) fails an M_Key
	check. After the lease period expires, clearing the M_Key
	protection bits allows any SM to read (and then set) the M_Key.
	Set this field to 0 to indicate that the lease period is never to
	expire. Refer to section 14.2.4, “Management Key, InfiniBand®
	Architecture, Vol. 1, Release 1.0”, for more information.”
