For information on the NetFPGA-1G NIC module and how to port it on the new 10G platform, visit NetFPGA-1G Ported Switch 10G.

The ported 1G NIC on NetFPGA is similar to other NICs. In the following sections, we will show how to run a iperf test between NetFPGA and another machine.

Testing Hardware

To run the test, you need two machines, A and B. Let's say Machine A is equipped with NetFPGA and Machine B is equipped with a third-party 1G NIC.

Download the proted_nic_1g bitfile from contrib-projects/ported_nic_1g/bitfiles/ported_nic_1g.bit. (Refer to Production Test Manual if you don't know how to download the bitfile and/or not setup JTAG cable yet.)

Connect Machine A and Machine B using a 1G cable (you will need a SFP-CAT5 converter if you use regular CAT5/6 copper cable). Assume we use nf0 (the port nearest to the PCI Express) on Machine A and eth1 on Machine B.

Build and Install the NetFPGA-10G NIC Driver

Here is a Quick Start.

Setup IP address

On Machine A

sudo ifconfig nf0

On Machine B

sudo ifconfig eth1

Test 1: Ping

On Machine A

[hyzeng@machine_A ~]$ ping

PING 56(84) bytes of data.

64 bytes from icmp_req=1 ttl=50 time=1.04 ms

64 bytes from icmp_req=2 ttl=50 time=1.04 ms

64 bytes from icmp_req=3 ttl=50 time=1.04 ms

64 bytes from icmp_req=4 ttl=50 time=1.04 ms

Test 2: iperf

iperf is a utility to measure the performance over an IP link.

First, make sure you have iperf installed on both machines. If not,

sudo yum install iperf 

Setup iperf server on Machine A.

iperf -s

Setup iperf client on Machine B.

[hyzeng@machine_B ~]$ iperf -c


Client connecting to localhost, TCP port 5001

TCP window size:  132 KByte (default)


[  3] local port 52787 connected with port 5001

[ ID] Interval       Transfer     Bandwidth

[  3]  0.0-10.0 sec  9.35 GBytes  935 Mbits/sec
