Hi,
We have an issue, between Cisco nexus 5k5 and Dell PowerEdge M1000e switch.
We try to connect with double twinax between nexus and dell switch in programmable-mux mode, as show the image, and when the main connection, form dell switch to nexus, is lots the server has no connectivity, even the other dell switch never lost de connectivity to de nexus.
Image may be NSFW.
Clik here to view.
