To provide a comprehensive overview we explain where each Nexus model is best positioned in the Data Center and directly compare high-end Nexus switches (Nexus 9000/7000) with high-end Catalyst switches (Catalyst 6800 / 6500) examining specifications, bandwidth – capacity, modules and features ( High-Availability, Port Scalability, VDC, vPC – VSS, OTV, VXLAN, etc).įor our readers convenience we have made available for free download over 90 different datasheets in our Cisco Data Center download section.įollowing are the topics covered in this article: between Nexus NX-OS and Catalyst IOS operating systems. We explain the differences between Nexus and Catalyst switches but also compare commands, naming conventions, hardware capabilities etc. This article introduces the Cisco Nexus product family (Nexus 9000, Nexus 7000, Nexus 5000, Nexus 3000, Nexus 2000, Nexus 1000V and MDS 9000).

I then output 2 columns as a text file (65508 lines), first column being the frequency and the second column being the SPL delta from the 3rd worksheet.I then loaded both files into a spreadsheet in different worksheets and subtracted the calibrated SPL column from the un-calibrated SPL calibrated column creating a new delta column in a 3rd worksheet.I edited the text files to remove the file and column header information leaving only the 3 measurement numeric columns (frequency, SPL and phase). I used the "File/Export Measurement as Text" option to do a text dump of the calibrated and un-calibrated files.The derived ECM8000 calibration SPL measurement(BLUE) tracks pretty close to the GREEN baseline, but the phase is a bit off at the ends.
