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

[MRees4]

Hi,

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.

Details:

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.

Thanks

Hi Arrambios,

Thank you for posting your issue in Intel wired ethernet communities.Any changes or update on the system prior to encountering the issue? you may want to do additional testing such as forcing the speed to 1Gbps on X540-T1 and Cisco switch port for isolation.you can also run System support utility on the affected system and share to us the output file.System support utility - https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utilityregards,Vince

Hi,

Based on the logs, you also have an onboard I218-LM network controller, does the login delay also occurs on that connection?We have new driver package version 21 posted in our download center, you may want to try it out. https://downloadcenter.intel.com/download/18713/Intel-Network-Adapter-Driver-for-Windows-7-Regards,Vince

Hi

You can close this case.

We have determined that the problem was an improper switch configuration.

the Cisco Nexus 3000 switch did not have Portfast turned on.

(for future individuals the correct command is : spanning-tree port type edge)

(And it didn't matter the device, card or port speed of the device connected, always took 50+ seconds to allow traffic flow.)

Thanks for your help.
