Network Adapter is up, but green light not lit

Hello Everyone,

I have 2 LACP, one for data, and one for service.

The service one, has 4 networks adapters, and all of them are working just fine. I can see in the VDs that all leds are lit.

Although, the data LACP has 2 leds that are not lit. The network adapters are up and connected physically on the switch.

Do you have any idea what might be the problem?

Regards,

Bruno

Hi Brunouerrasousa,

From VMware end we are seeing Link status is up, Ideally in this scenario you should able to see the Led lit on the switch.

If possible unplug or swap the cable and see any difference on the switch.

esxcli network nic down -n vmnic<no>  command will down the nic in Esxi host, on switch show configuration should show link down.

Might be issue with the switch port. Verify switch Firmware and configuration.

Thanks & Regards

Could you explain more on the vmnic numbering e.g. vmnic0, vmnic1, vmnic2, vmnic3 and how did you create the PortGroup and LACP

The network adapters in this LACP are vmnic12, vmnic13, vmnic14, vmnic15.

First, I created a vDS, then added the host in this vDS.

Under networking settings, I created the LACP with 4 ports.

Back in the host, I added the network adapters in the LACP. That´s it.

Am I missing something?

All portgroups of the VDs, are configured to use the LACP in the failover order.

Hello ArjunDooti

I checked the connectivity by running the command that you told me. Everything seems alright.

I attached the prints with the output.

I also checked the thoughput and seems that the data is going throught (check print "rfb6" we used esxcli network nic stats get -n vmnic) , so We don´t know why the nics icons are not green.

Thanks in advance.

how about the uplink physical switches configuration?
any high level/logical diagram?
how many physical switches, how they are being setup?

Hi, i'm also accompany this issue. First, thank you all for taking your time to help us!

So, if you are asking for the physical switch information, does it mean that on the side of the ESXi hosts everything is alright? The white icon means that someting is wrong with the  overall connection and not exactly on the ESXi side?

We gonna check how the physical part is!

Edited: We checked in our test enviroment what would happen to the icon if the port on the physical switch was down. If the switch port is down, the vsphere web interface shows the vminic with the red X but the adapter icon is still green! ( Image attached !). I'm truly confused now. Doe that adapter icon only shows if you have a cable physically connected to the host?

Hi Priscillarega,

nic driver and firmware update should resolve the issue.

Thanks & Regards

Hello!

We used the command "esxcli network nic down -n vmnic<no>" and then brought the vmnics up again. And guest, it worked. The adapter icon went green!

It was so simple haha

Thank you very much for the help!
