Preface

This chapter provides an introduction to the DNC10 Series network interface cards (NICs) with Wake-on-LAN (WoL).

This chapter contains the following sections:

☐ “Functional Description” on page 18
☐ "DNC10LC Fiber Optic Port" on page 20
☐ "DNC10SP SFP+ Port" on page 21
☐ "DNC10T Twisted Pair Copper Port" on page 23
☐ “Features” on page 25

Functional Description

The DNC10 Series network adapters are 10 Gigabit Ethernet (10GbE) interface controllers that are based on the Aquantia AQC100 10GbE media access controller (MAC) with integrated serializer/deserializer (SerDes).

The Aquantia diagnostic tool can be used with the device to provide firmware programming and a first level of diagnostics and fault isolation.

These cards have Peripheral Component Interconnect Express (PCIe) bus connectors. The DNC10 Series network adapters support the PCIe x4 v3.0, 2.1 and 1.1a compliant interfaces.

The AT-DNC10 Series can perform accelerated Ethernet data networking and storage networking simultaneously for all popular protocols used in the data center, and includes features such as Data Center Bridging.

Enterprise networks that use multiple protocols and multiple network fabrics benefit from the ability of the network interface card (NIC) to combine data communications, storage, and clustering over a single Ethernet fabric and to boost server CPU performance and memory utilization while alleviating I/O bottlenecks.

Wake-on-LAN (WoL) is a protocol for remotely turning on a computer in a low power mode with a network message. A magic packet is a network message that a WoL-enabled computer receives and wakes up when the computer's MAC address matches one in the magic packet.

As part of the company's green range, the adapter is engineered to reduce power consumption. It incorporates centralized power management features that automatically place idle circuitry into a lower power mode to save energy.

The basic characteristics of the NICs are listed in Table 1.

Table 1. DNC10 Series Network Interface Cards

Adapter Port Speed Cable Type				Maximum Distance	System Connection
DNC10SP SF	P+ 10G/1G Varies by		SFP+ transceiver	Varies by SFP+ transceiver	PCIe x4 (Gen 3)
DNC10LC Duplex LC 10G OM1 33m PCIe x4					(Gen 3)
				OM2		82m
				OM3		300m
				OM4 550m
DNC10T RJ45 10G CAT6A	100m PCIe x4				(Gen 3)
			5G/2.5G/1G/100M	CAT5e or CAT6A

Note

The maximum operating distance of the SFP+ port on the DNC10SP adapter depends on the transceiver. Refer to the product's data sheet on the Allied Telesis web site for a list of supported transceivers.

Recv Segment Coalescing (IPv4)

When receiving data, the miniport driver, NDIS, and TCP/IP must all look at each segment's header information separately. When large amounts of data are being received, this creates a large amount of overhead. Receive segment coalescing (RSC) reduces this overhead by coalescing a sequence of received segments and passing them to the host TCP/IP stack in one operation, so that NDIS and TCP/IP need only look at one header for the entire sequence.

To enable or disable the Receive Segment Coalescing (IPv4) feature, do the following:

1. Access the Advanced Properties.

See "Accessing Advanced Properties" on page 58.

1. Select Receive Segment Coalescing (IPv4) in the Property box.

The Receive Segment Coalescing (IPv4) page is displayed as shown in Figure 42.

1. Select one of the following options:

☐ Enabled — RSC is enabled. This is the default setting.

□ Disabled — RSC is disabled.

1. Click OK.

Recv Segment Coalescing (IPv6)

When receiving data, the miniport driver, NDIS, and TCP/IP must all look at each segment's header information separately. When large amounts of data are being received, this creates a large amount of overhead. Receive segment coalescing (RSC) reduces this overhead by coalescing a sequence of received segments and passing them to the host TCP/IP stack in one operation, so that NDIS and TCP/IP need only look at one header for the entire sequence.

To enable or disable the Receive Segment Coalescing (IPv6) feature, do the following:

1. Access the Advanced Properties.

See "Accessing Advanced Properties" on page 58.

1. Select Receive Segment Coalescing (IPv6) in the Property box.

The Receive Segment Coalescing (IPv6) page is displayed as shown in Figure 43.

TCP/UDP Checksum Offload (IPv4)

The TCP/UDP Checksum Offload (IPv4) function enables the adapter port to compute the checksum of transmitting IPv4 packets and verify the checksum of receiving IPv4 packets, taking load off from the CPU.

To modify the TCP/UDP Checksum Offload (IPv4) setting, do the following:

1. Access the Device Manager on your operating system.

See "Accessing Advanced Properties" on page 58.

1. Select TCP/UDP Checksum Offload (IPv4) in the Property box.

The TCP/UDP Checksum Offload (IPv4) page is displayed as shown in Figure 44.

Figure 44. TCP/UDP Checksum Offload (IPv4) Page

1. Select one of the following options:

☐ Rx & Tx Enabled — Enables the TCP/UDP Checksum Offload (IPv4) function for both receiving and transmitting IPv4 packets. This is the default setting.

□ Disabled — Disables the TCP/UDP Checksum Offload (IPv4) function for both receiving and transmitting.

☐ Rx Enabled — Enables the TCP/UDP Checksum

Offload (IPv4) function only for receiving IPv4 packets.

☐ Tx Enabled — Enables the TCP/UDP Checksum Offload (IPv4) function only for transmitting IPv4 packets.

1. Click OK.

TCP/UDP Checksum Offload (IPv6)

The TCP/UDP Checksum Offload (IPv6) function enables the adapter port to compute the checksum of transmitting IPv6 packets and verify the checksum of receiving IPv6 packets, taking load off from the CPU.

To enable or disable the TCP/UDP Checksum Offload (IPv6) feature, do the following:

1. Access the Device Manager on your operating system.

See "Accessing Advanced Properties" on page 58.

1. Select TCP/UDP Checksum Offload (IPv6) in the Property box.

The TCP/UDP Checksum Offload (IPv6) page is displayed as shown in Figure 45.

1. Select one of the following options:

☐ Rx & Tx Enabled — Enables the TCP/UDP Checksum Offload (IPv6) function for both receiving and transmitting IPv6 packets. This is the default setting.

□ Disabled — Disables the TCP/UDP Checksum Offload (IPv6) function for both receiving and transmitting.

☐ Rx Enabled — Enables the TCP/UDP Checksum

Offload (IPv6) function only for receiving IPv6 packets.

☐ Tx Enabled — Enables the TCP/UDP Checksum Offload (IPv6) function only for transmitting IPv6 packets.

1. Click OK.

Transmit Buffers

The number of transmit buffers. Transmit buffers are data segments that allow the network adapter to monitor transmit packets in the system memory.

To specify or change the Transmit Buffers feature, do the following:

1. Access the Device Manager on your operating system.

See "Accessing Advanced Properties" on page 58.

1. Select Transmit Buffers in the Property box.

The Transmit Buffers page is displayed as shown in Figure 46.

Figure 46. Transmit Buffers Page

1. Specify the buffer size in the Value box. The valid range is 256 to 8184 in increments of 8. The default value is 2048

2. Click OK.

VLAN ID

The VLAN ID property allows you to specify a VLAN ID on your network to the adapter port. The adapter port adds the value of the VLAN ID to a frame in the VLAN tag before transmitting the frame.

To change the VLAN ID value, do the following:

1. Access the Advanced Properties.

See "Accessing Advanced Properties" on page 58.

1. Select VLAN ID in the Property box.

The VLAN ID page is displayed as shown in Figure 47.

Figure 47. VLAN ID Page

1. Specify a VLAN ID in the Value box.

The range of the value is from 0 to 4094. The default value is 0. Leaving the VLAN ID set to 0 will result in no VLAN tag being added to egress packets, even if VLAN is enabled. This field must be set to the desired VLAN ID if VLAN headers are desired.
