NOTE: The maximum number of VFs supported by software is 128 VFs per device.
 Number of MSI-X Vectors per VF
This setting allows the user to configure the MSI-X Vectors per VF. Message Signaled Interrupts (MSI) are an alternative
in-band method of signaling an interrupt, using special in-band messages to replace traditional out-of-band assertion of
dedicated interrupt lines. This is a numeric setting. The maximum number of virtual functions supported by the adapter
are shared across the number of physical ports on the adapter. This value must be specified only in multiples of 8.
 Maximum Number of PF MSI-X Vectors – This setting allows the user to configure the Maximum Number of MSI-X
Vectors for a physical function. This is a numeric setting. The minimum value for this setting is 0. The maximum value
varies across adapters.
 Link FEC – This setting configures the Forward Error Correction (FEC) mode which is a technique used for controlling
errors in data transmission over unreliable or noisy communication channels. This option is useful when longer fiber
cables are utilized. This setting is not available on 10GBASE-T controllers. This setting is not available on 10G BaseT
controllers. Only a subset of the possible values display on some adapters, based on the configuration. Possible values
are:
– Disabled
– CL74 – Fire Code
– CL91 – Reed Solomon
– RS544 – RS544, using 1 x N RS
– RS272 – RS272, using 1 x N RS
– RS544 – RS544, using 2 x N RS
– RS544 – RS544, using 2 x N RS
NOTE: When Media Auto Detect and Auto-negotiation is enabled, FEC is negotiated based on the link partner
advertisement.
 Energy Efficient Ethernet – This setting configures the Energy Efficient Ethernet (EEE) mode which are a set of
enhancements that allow for less power consumption during periods of low-data activity. This setting is available only
on 10GBASE-T controllers.
– Enabled – Turn on EEE mode
– Disabled –Turn off EEE mode
 Operational Link Speed – This setting configures the default link speed for pre-OS environment in full-power (D0)
state. The possible values for this setting depends on the link speeds supported by the adapter.
NOTE: The value for this setting is fixed on some adapters based on the configuration."
 DCB Protocol – This setting configures the Data Center Bridging (DCB) settings for the controller. Some of the
following options may not be available depending on the adapter in use.
– Enabled (IEEE only)
– CEE (only)
– Both (IEEE preferred with fallback to CEE)
 LLDP nearest bridge – This setting configures the Link Layer Discovery Protocol (LLDP) which is a vendor-neutral link
layer protocol used by network devices for advertising their identity, capabilities, and neighbors on a local area network
based on IEEE 802 technology, principally wired Ethernet. An LLDP agent is a mapping of an entity where LLDP runs.
– Enabled – Turn on LLDP nearest bridge
– Disabled – Turn off LLDP nearest bridge
 LLDP nearest non-TPMR bridge – This setting configures the Link Layer Discovery Protocol (LLDP) which is a
vendor-neutral link layer protocol used by network devices for advertising their identity, capabilities, and neighbors on a
local area network based on IEEE 802 technology, principally wired Ethernet. An LLDP agent is a mapping of an entity
where LLDP runs. This setting enables LLDP on the nearest non-TPMR bridge agent.
– Enabled – Turn on LLDP nearest non-TPMRbridge
– Disabled – Turn off LLDP nearest non-TPMRbridge
