Interface errors on NE1032

2021-06-30, 18:06 PM

We are seeing input and output errors on 10G-T SFP+ connected interfaces on a Lenovo NE1032.   The 10G interfaces on the HX3310 servers have 10G-T interfaces, so we are using CAT6 RJ-45 cables and the Lenovo 10G RJ-45 SFP+ modules in the SFP+ ports.

 

We replaced a LOM on one of the servers last year due to errors on the interface, but now we are seeing what looks like the same issue on the others ports.   But there are erorrs on all of the ports.   

 

Is this a NE1032 issue or is it a HX hardware issue?

Hello timster68,

 

Thanks for providing the show tech. Can you please tell us what ports you are concerned about and what type of errors you are seeing? Also, are you noticing an issue? I know this may seem like a weird question but what made you look at these ports?

It's ports 1-3-7.

 

We are seeing input errors and resets on those three interfaces.   The Lenovo and Nutanix support reps said they are seeing interface errors on the hypervisor.

At first glance, the article below seems to cover your issue pretty well:

 

https://datacentersupport.lenovo.com/us/en/products/networking/rackswitch/ne1032t/7159/solutions/ht507781-when-switch-port-is-connected-over-1g-speed-packet-drops-and-symbol-errors-may-occur-lenovo-rackswitch

 

When you get a chance try upgrading the firmware to the latest available.

 

Another thing I noticed while looking at the input errors is that they are happening on port 7 (which the logs indicate the interface going up a down a lot) and 31. This could indicate a hardware issue either with the SFP or the cable on either side. If the input errors are related to CRC issues then in my experience it is usually the cable, the SFP on the other side of the switch, or the network interface on the other side.

 

My recommendation is to first upgrade the switch and resolve the time to easily follow the logs. A reboot should clear the counters and then they can be monitored from there to see if the issue persists.

 

Please let me know if you have any questions or concerns.

Hello Timster,

 

I would start by upgrading to the latest 10.10 version of code. I know there have been a lot of issues with errors on 1G interfaces in even early 10.10 code, much less 10.9 and earlier, in particular RJ45 1G errors, and perhaps they would impact RJ45 10G as well. The current latest code for your switch can be found here:

https://download.lenovo.com/servers/mig/2021/06/02/53962/lnvgy_fw_torsw_ne1032-cnos-10.10.9.0_anyos_noarch.zip

I've attached a PDF that covers upgrades, with page 3 covering your environment.

 

I would also look closer at eth 1/7 specifically, as it seems to have a different set of error conditions than ports 1 and 3. In looking at "show interface counters errors" we see FCS errors on port 1/7, as well as runts being reported, all of which seem to be pointing at a potential layer 1 issue on this path (primary suspects would be either the 10GBaseT module in the switch or server side, or the cable in between, with a lesser likelihood of a bad switch port or a bad server NIC on this path.

 

Either way I would still strongly recommend the code upgrade as there are a lot of critical fixes as well as improvements.

 

Please let us know if replacing components in the eth 1/7 path and/or the code upgrade resolves your issue, and if not, please send a fresh show tech after the troubleshooting/upgrade and we can review further.

 

Thanks, Matt

Thanks for the doc and the download.   We will upgrade this Friday.   I will update the thread when we are done.

@timster68 

 

Checking in to see how the upgrade went last week. Are you still experiencing the same issues? If so, please let us know how we can help.

 

If everything is looking good please consider marking one of these posts as the resolution to this thread.

We upgraded the firmware on the switch and the same host went offline again.   We are working on replacing the components between the switch and the host.
