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.”
