This next article in this mini-series about testing Ethernet/IP networks I will write about one of the most common test – the RFC2544 ”Bench-marking Methodology for Network Interconnect Devices”. The purpose of this test is quite often misunderstood even though it is clearly stated in the introduction of the standard itself. So let’s start with clarifying what this testing suite is and what it should be used for.
This article will be rather short in comparison with the others in the mini-series about various Ethernet/IP testing methods but it is one that is necessary as Bit Error Tests have a long tradition in telco environment (circuit based networks) but are still quite valid even in nowadays packet networks – at least for some specific cases. So without further delay let start with some theory behind the testing and some practical use followed by some use cases and best practices.
This is just quick how-to on setting up vlan interface on a Linux system. As this is in lengths described elsewhere I will stick just to the commands and brief explanations.
