Hi Ulf, I am currently running a fabric path setup with four Nexus 5548UP for a customer. We had several problems followed by mysterious packet loss when upgrading from NX-OS 5.2(1)N1(4) to 7.0(5)N1(1) in case of leap second update. Cisco TAC advised me to downgrade after the event on 1st of July in 2015 due to CSCuo56514. This Bug should first be fixed in 7.0(7)N1(1). Presently this is the recommended IOS-XE for N5K. My customer is currently running 5.2(1)N1(9) without any problems.

It hasn't been giving us problems, with the exception of several bad Cisco direct attached copper cables. On Mon, Mar 7, 2016 at 7:55 AM, Nicolas V <nicovpp59@gmail.com> wrote:

Hello,

Does anyone already played with cisco fabricpath feature ? I want to use it on my nexus 5548

Is it working as easy as it seems ? No bugs / particular nx-os version... ?

Thanks ! Nicolas
