Advanced settings for HP NC-Series Mellanox 10GbE adapters

These advanced parameters are available for HP NC-Series Mellanox 10GbE Server Adapters.

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

Some properties are not available for FlexNIC-enabled adapters.

• 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
• 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.
  • Default = 1514 Bytes
  • Range = 1514 Bytes; 4088 Bytes; 9014 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 = Disable; Tx Enable; Rx Enable; Rx/Tx Enable
• TCP/UDP Checksum Offload (IPv4). Describes whether the device enabled or disabled the calculation of TCP or UDP checksum over IPv4 packets. If this TCP/UDP Checksum Offload (IPv4) property is present, it overrides the TCP Checksum Offload (IPv4) and UDP Checksum Offload (IPv4) properties and they are disabled.
  • Default = Rx/Tx Enable
  • Range = Disable; Tx Enable; Rx Enable; Rx/Tx Enable
• TCP/UDP Checksum Offload (IPv6). Describes whether the device enabled or disabled the calculation of TCP or UDP checksum over IPv6 packets. This property overrides the TCP Checksum Offload (IPv6) and UDP Checksum Offload (IPv6) properties. If TCP/UDP Checksum Offload (IPv6) is present, TCP Checksum Offload (IPv6) and UDP Checksum Offload (IPv6) properties are disabled.
  • Default = Rx/Tx Enable
  • Range = Disable; Tx Enable; Rx Enable; Rx/Tx Enable
• Large Send Offload Version 1 (IPv4). Describes whether the device enabled or disabled the segmentation of large TCP packets over IPv4 for large send offload version 1 (LSOv1).
  • Default = Rx/Tx Enable
  • Range = Disable; Tx Enable; Rx Enable; Rx/Tx Enable
• 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).
  • Default = Rx/Tx Enable
  • Range = Disable; Tx Enable; Rx Enable; Rx/Tx Enable
• 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).
  • Default = Rx/Tx Enable
  • Range = Disable; Tx Enable; Rx Enable; Rx/Tx Enable
