Chapter XVII. WD Sniffing and Tracing

2. Installation and Usage

2.1.

Installing basic support

iw_cxgb4 (Chelsio iWARP driver) and cxgb4 (Chelsio NIC driver) drivers have to be compiled
and loaded before running the utilities. Refer to the Software/Driver Loading section for each
driver and follow the instructions mentioned before proceeding.
2.2.

Using Sniffer (wd_sniffer)

1. Setup:
Wire filter sniffing requires 2 systems with one machine having a T5/T4 card.
The machines should be setup in the following manner:
Machine A
192.168.1.100
2. Procedure:
On the Device Under Test (DUT), start sniffer.
[root@host~]# wd_sniffer -T 20 -s 1000 -I <MAC address of interface to
sniff>
Start traffic on the PEER and watch the sniffer.
The sniffer will receive all packets as fast as possible, update the packet count, and then
discard the data. Performance is a full 10Gbps for packet size 1000.
2.3.

Using Tracer (wd_tcpdump_trace)

1. Setup:
Wire tapping requires 3 systems with one machine having a T5/T4 card with two or more ports.
The machines should be setup in the following manner:
Chelsio T5/T4 Unified Wire for Linux
<---------> Machine B
192.168.1.200
