Symptoms
If intermittent packet loss is encountered on Dell PowerEdge servers with Dell OEM Intel E810-C adapters (DPN: VK88G or CD16M) with VMware NSX-T configured, the investigation may lead to an issue described by the following VMware KB article:
Intermittent packet loss may occur when bridging is configured on NSX (95979) (vmware.com)
If a customer follows the instruction of the "Resolution" mentioned in the above VMware KB article, to disable the VMDQ loopback feature using the Intel esxi-plugin tool ("intnetcli"), an error "Device vmnicX is not supported" would be seen after issuing the suggested command:
The same failure exists on the Intel E810 card running on 22.5.7 firmware and icen 1.12.5.0 driver, or an earlier Firmware Driver combination under VMware ESXi 7.0.3 or 8.x.
Cause
Intel E810 adapter on 1.12.5.0 or earlier icen driver does not support disabling the VMDQ loopback feature.
Resolution
Fix:
Intel has provided the fix for disabling the VMDQ loopback feature in the icen driver 1.14.2.0 for both ESXi 7.x and 8.x.
Upgrade to this new driver with the corresponding firmware release plus install the Intel esxi-plugin tool ("intnetcli") 1.13.0.25.
