Advanced settings for HP NC-Series Broadcom 1 GbE adapters

These advanced properties are available for HP NC-Series Broadcom 1 Gigabit Server Adapters. Each adapter property displays only if the property is supported by the selected adapter.

• 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 = 1324 Bytes; 1514 Bytes; 4088 Bytes; 9014 Bytes
• Wake Up Capabilities. Determines the type of packets that will cause the adapter to wake up the system.
  • Default = Both
  • Range = None; Magic Packet; Wake Up Frame; Both
• Flow Control. Determines the type of flow control that is needed.
  • Default = Rx/Tx Enable
  • Range = Disable; Tx Enable; Rx Enable; Rx/Tx Enable
• Ethernet at Wire Speed. Enables linking at 100 Mbps when using a cable that does not support Gigabit speed.
  • Default = Enabled
  • Range = Disabled; Enabled
• WOL Speed. Specifies the speed at which the adapter connects to the network during Wake-on-LAN mode.
  • Default = Auto
  • Range = Auto, 10Mb, 100Mb
• IPMI. Enables Intelligent Platform Management Interface, which provides a means for monitoring, control, and automatic recovery of servers. IPMI can only be enabled on one port at a time. IPMI cannot be enabled on a port that has Large Send Offload enabled.
  • Default = Disabled
  • Range = Disabled; Enabled
• Number of Tx Descriptors. Determines how many resources are allocated to transmit packets.
  • Default = 200
  • Range = 100–600
• Number of RX Descriptors. Determines how many resources are allocated to receive packets. Increasing receive descriptors can increase performance, which also increases the amount of system memory used by the driver. So, if too few receive descriptors are used, performance suffers and if too many receive descriptors are used the driver unnecessarily consumes memory resources. Setting the number of receive descriptors to a higher value, might result in BSODs, system reboots, or other unexpected results.
  • Default = 200
  • Range = 3000–5000
• 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 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
• UDP Checksum Offload (IPv4). Describes whether the device enabled or disabled the calculation of UDP checksum over IPv4 packets.
  • Default = Rx/Tx Enable
  • Range = Disable; Tx Enable; Rx Enable; Rx/Tx Enable
• TCP/UDP/IP Checksum Offload (IPv4). Describes whether the device enabled or disabled the calculation of TCP, UDP, or IP checksum over IPv4 packets. If this TCP/UDP/IP Checksum Offload (IPv4) property is present, it overrides and disables the TCP Checksum Offload (IPv4), UDP Checksum Offload (IPv4), and IPv4 Checksum Offload properties.
  • Default = Rx/Tx Enable
  • Range = Disable; Tx Enable; Rx Enable; Rx/Tx Enable
• TCP Checksum Offload (IPv6). Describes whether the device enabled or disabled the calculation of TCP checksum over IPv6 packets.
  • Default = Rx/Tx Enable
  • Range = Disable; Tx Enable; Rx Enable; Rx/Tx Enable
• UDP Checksum Offload (IPv6). Describes whether the device enabled or disabled the calculation of UDP checksum over IPv6 packets.
  • Default = Rx/Tx Enable
  • Range = Disable; Tx Enable; Rx Enable; Rx/Tx Enable
• TCP/UDP/IP Checksum Offload (IPv6). Describes whether the device enabled or disabled the calculation of TCP, UDP, or IP checksum over IPv4 packets. If this TCP/UDP/IP Checksum Offload (IPv6) property is present, it overrides and disables the TCP Checksum Offload (IPv6), UDP Checksum Offload (IPv6), and IPv6 Checksum Offload properties.
  • 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 = Enabled
  • Range = Disabled; Enabled
• 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 = Enabled
  • 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).
  • Default = Enabled
  • Range = Disabled; Enabled
