I am using a software tool that I did not write and do not have access to the source of to introduce Bit Errors into an Ethernet Network. I am currently trying to test to see whether this software does what it actually is supposed to do, so that it can be used in some network simulations. I know
Ethernet Bit Error Rate Standard
there are hardware testers like the FireBERD but it would be great if someone had some software that could do it. Although based on what I'm reading here http://www.wireshark.org/faq.html#q7.9 I don't have much hope. networking wireshark packet-loss share|improve this question edited Aug 19 '11 at 17:38 Diogo 19.8k47118194 asked Aug 19 '11 at 17:22 rhololkeolke 243312 If you have a Mac handy, it might be worth trying Wireshark on that. I've never seen Wireshark capture CRC data on any Windows machines. –sblair Aug 19 '11 at 18:21 add a comment| 5 Answers 5 active oldest votes up vote 2 down vote If you're running *NIX you can check /proc/net/dev to see stats about errors. It's vague about what errors, but according to this post on Stackoverflow it does record CRC errors. share|improve this answer answered Aug 19 '11 at 18:49 charlesbridge 936611 This is interesting and potentially useful, however, the errors are at a packet level and I need something that will give me errors on the bit level. In our initial testing we were using Wireshark and looking at packets that we knew were incorrect and trying to count bits. Obviously this is not going to work for a lot of packets so we need software that can detect errors on the bit level and give us statistics based on them. –rhololkeolke Aug 22 '11 at 16:32 add a comment| up vote
Results Other VoIP Products | Application Notes | Buyer's Guide Overview GL's enhanced PacketCheck™ is a comprehensive PC free download bit error rate tester software based Ethernet / IP test tool with BERT and Throughput free ethernet testing software testing abilities. It is very easy to use as a general purpose network performance analysis tool
Bit Error Rate Example
for 10Mbps, 100Mbps and 1Gbps LANs and WANs. Throughput up to 800 Mbps can be easily tested. The application truly takes confusion out of Ethernet http://superuser.com/questions/325328/how-to-test-bit-error-rates-on-ethernet-networks testing at all protocol layers - from raw Ethernet frames to IP/UDP packets. PacketCheck™ makes use of PC's network interface card (NIC) to transmit and receive Ethernet or IP packets over the network. The application generates multi stream Ethernet/IP/UDP traffic with on-demand bandwidth (up to 800 Mbps) and measures end to http://www.gl.com/packetcheck.html end performance such as Bit Error Rate, Total Packets, Packet loss, Out of Sequence Packets, and Erred Packets. Additional features include transmission of pre-recorded file traffic, GTP traffic simulation, Bursty and Fixed IFG (Inter Frame Gap) traffic generation mode, Delay measurements, impairment generation, and BER testing capability with provision to generate PRBS patterns or user–defined test patterns. User's Guide Quick Install Guide Product Brochure PacketCheck™ Vs PacketExpert™ View Presentation GL Product Lists It also includes a Command Line Interface (CLI) to support all the GUI functionalities of PacketCheck™ through simple commands, allowing easy scripting and automation of the testing. Also included is a powerful Report Generation feature to view report in XML and PDF formats. PacketCheck™ can operate on any of the layers - Layer 1 (Physical), Layer 2 (Data Link), Stacked VLAN (Q-in-Q), Layer 2.5 (Stacked MPLS), Layer 3 (Network), and Layer 4 (Transport) of the OSI reference model.
