Ethernet property. These adapter properties display only if the property is supported by the selected adapter.

Some properties are not available on Flex-NIC-enabled adapters.

• Maximum Frame Size. Specifies the maximum number of bytes in a single packet. Larger frames can increase throughput and decrease CPU use by putting more data in each packet, thereby sending out fewer packets. This is equivalent to Jumbo Frames and must comply with switch limitations.
  • Default = 1514 Bytes
  • Range = 1514 Bytes; 4088 Bytes; 8014 Bytes
• Flow Control. Specifies the type of flow control that is needed.
  • Default = Enabled
  • Range = Disabled; Enabled
• 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.
• IPv4 Checksum Offload. Describes whether the device enabled or disabled the calculation of IPv4 checksums.
  • Default = Rx/Tx Enable
  • Range = Range = Disable; Tx Enable; Rx Enable; Rx/Tx Enable
• Large Send Offload. Enables offloading of large TCP packets.
  • Default = Enabled
  • Range = Disabled; Enabled
• Priority and VLAN. Enables or disables the ability to insert or remove the 802.1q tags for priority and VLAN.
  • Default = Priority & VLAN Enabled
  • Range = Priority & VLAN Disabled; Priority & VLAN Enabled; Priority Enabled; VLAN Enabled
• TCP Checksum Offload (IPv4). Describes whether the device enabled or disabled the calculation of TCP Checksum over IPv4 packets.
  • Default = Rx/Tx Enable
  • Range = Disable; Tx Enable; Rx Enable; Rx/Tx Enable
