What does the X change other than 4k in price difference? I can't find any difference between the child parts, and the datasheets don't detail the difference and the part number descriptions are exactly the same. I have a lot of questions like this a...

Hi all, i'm in a migration path from and old 65K infrastructure to a new one with Nexus 9000. The datacenter network has only one single Cisco Nexus switch that connect to a couple of ASA 5585 in A\S configuration. What should be the best way to con...

I know that in order to connect the 2348TQ (6x40G uplink) to the 9372PX I need to use breakout cables with appropriate SFPs.  My question is, is there any configuration to be done in order for the 2348 uplinks to work in this mode.  Can I just create...

I'm late to this project, short deadline and no real experience with the hardware.  Typical story :) I've had zero exposure to UCS and Nexus but I have a good understanding of IOS switching.  I'm confused as to why the existing solution connects the ...
