    40 sec negotiation with X540-T1 with Cisco Nexus 3172TQ



      Have a client experiencing the following issue - when they boot or reboot a workstation, the LAN adapter takes 40+ seconds to negotiate with the LAN switch before it connects.



      Workstations are Windows 7 Pro with Intel Ethernet Converged Network Adapter X540-T1 running SSD drives. So they boot within seconds, and when the users go to sign on, system connects before network is available, thus network maps are not completed, etc. Once the system negotiates the link and is online, a log off / log on cycle works properly. (And the users tend to forget between system reboots that they need to be patient. Thus wasted support calls troubleshooting.)



      Switch is Cisco Nexus 3172TQ (48 port 10GBase-T)

      Cisco firmware has been patched recently.


      Any suggestions on what to focus on / investigate in depth? Opening a case with Cisco as well. Will also look for Cisco commands etc.
