Adapter configurations 36
o Default for NC6170 and NC7170 adapters = No Action
o Range for NC6170 and NC7170 adapters = Disabled; Enabled; Hardware Default; No Action
• Flow Control. Determines the type of flow control that is needed. Flow control enables the
transmission of PAUSE frames. Not supported on NC71xx adapters.
o Default = Rx/Tx Enable
o Range = Disable; Tx Enable; Rx Enable; Rx/Tx Enable
• Gigabit Master Slave Mode. Determines IEEE 802.3ab Master-Slave resolution during gigabit auto
negotiation.
o Default = Auto Detect
o Range = Auto Detect; Force Master Mode; Force Slave Mode
• Interrupt moderation. If enabled, helps to reduce number of interrupts per packet, which reduces
CPU utilization, while maintaining the same throughput. This feature is useful under heavy network
traffic conditions.
o Default = Enabled
o Range = Disabled; Enabled
• Interrupt moderation rate. Determines the amount of interrupts per second when the Interrupt
moderation parameter is enabled.
o Default = Adaptive
o Range = Adaptive; Extreme; High; Low; Medium; Minimal; Off
• IPv4 Checksum Offload. Describes whether the device enabled or disabled the calculation of IPv4
checksums.
o Default = Rx/Tx Enable
o Range = Disable; Tx Enable; Rx Enable; Rx/Tx Enable
• Jumbo Packet. The size, in bytes, of the largest supported Jumbo Packet (an Ethernet frame that is
greater than 1514 bytes) that the hardware can support.
o Default = Disabled
o Range = 4088 Bytes; 9014 Bytes; Disabled
• Large Send Offload Version 2 (IPv4). Describes whether the device enabled or disabled the
segmentation of large TCP packets over IPv4 for large send offload version 2 (LSOv2).
o Default = Enabled
o Range = Disabled; Enabled
• Large Send Offload Version 2 (IPv6). Describes whether the device enabled or disabled the
segmentation of large TCP packets over IPv6 for large send offload version 2 (LSOv2).
o Default = Enabled
o Range = Disabled; Enabled
• Link Speed & Duplex. Sets the connection speed to the network and mode. Full-Duplex Mode allows
the adapter to transmit and receive network data simultaneously. This property is not available for
NC310F and NC61xx adapters through the Microsoft® User Interface.
o Default = Auto Negotiation
o Range for NC340x and NC71xx adapters: Auto Negotiation; 10Mbps/Half-Duplex;
10Mbps/Full-Duplex; 100Mbps/Half-Duplex; 100Mbps/Full-Duplex; 1.0 Gbps/Full-Duplex
