Created attachment 859349 [details] TestResults.tar.gz Description of problem: When using the hwcert-client-1.7.0-20140124.2 the TCP-throughput portion of the network test fails on a RHEL7 snapshot 4 host with two 1Gb NICs. However, on the same RHEL7 host the hwcert-client-1.7.0-62.1 network test passes. The same remote test server was used for each test run. So far this behavior has been seen on two servers with different 1Gb NICs. The attached TestResults.tar.gz contains the xml results package from each of the above test runs as well as the sosreport from the host. When using hwcert-client-1.7.0-20140124.2 or later is the same kit required on the remote test server? Version-Release number of selected component (if applicable): hwcert-client-1.7.0-20140124.2 - network test fails hwcert-client-1.7.0-62.1 - network test passes How reproducible: always Steps to Reproduce: 1.Install RHEL7 snapshot 4 on a server with 1Gb NICs. 2.Install required cert kit components: dt-15.14-2.EL6.x86_64.rpm lmbench-3.0a7-6a.EL6.x86_64.rpm stress-0.18.8-1.3.EL6.x86_64.rpm seabios-1.7.2.2-10.el7.x86_64.rpm 3.Install cert kit: hwcert-client-info-1.7.0-20140124.2.el7.noarch.rpm hwcert-client-1.7.0-20140124.2.el7.noarch.rpm 4. Remote test server setup RHEL6.2 dt-15.14-2.EL6.x86_64.rpm lmbench-3.0a7-6a.EL6.x86_64.rpm stress-0.18.8-1.3.EL6.x86_64.rpm hwcert-client-info-1.6.4-57.el6.noarch.rpm hwcert-client-1.6.4-57.el6.noarch.rpm hwcert-server-1.6.4-57.el6.noarch.rpm 5. Run host network test. Actual results: The network TCP-throughput portion of the test always fails with following error: TCP-throughput: testing bandwidth to 10.5.2.43 bw_tcp -P 2 -m 1m 10.5.2.43 Error: tcp bandwidth test failed bw_tcp errors: 1.048576 129.19 MB/sec "bw_tcp -P 2 -m 1m 10.5.2.43" has output on stderr FAIL On the same host when using hwcert-client-1.7.0-62.1 the network TCP-throughput results are as follows: TCP-throughput: testing bandwidth to 10.5.2.43 bw_tcp -P 2 -m 1m 10.5.2.43 1.048576 137.45 MB/sec 1.048576 139.05 MB/sec 1.048576 129.50 MB/sec 1.048576 127.99 MB/sec 1.048576 130.26 MB/sec Average Bandwidth: 132.85 PASS Expected results: The network test should pass since the 129.19MB/sec throughput is an acceptable throughput for a 1Gb NIC.
