Finally hardcoded the speed on both ends and it is consistent. Doesn't change! But I'll be running speed tests next week. Thanks for the ethtool information! Chris

Thanks! The servers are in the same rack as the two Nexus 3172TQ switches are installed. So it's like 3 meters. What we wound up doing was to set the NICs/Ports to 10Gb Full Duplex on both ends. I'll be testing actual speed next week. Chris ...

Oddest Thing I've Ever Seen - ioFusion Cards cause IP Ping Loss in VMs

Cisco UCS Infra. FW Update - One ESXi host loses connection the other doesn't

Strange Network behavior - losing pings when re-enabling network uplink on 6248UP FI
