Esxi 6.7 VM packet drops on standard vSwitch wi… |VMware Communities

We experienced the same issue.

Hosts on VMware ESXi, 6.7.0, 11675023.

Seems to be a bug with IP HASH.

We disabled etherchannel on our Cisco 3850 stack and using Port ID instead.

This resolves the packetloss. Spoke to a network engineer and confirmed the bug.

They can create a workaround for you remotely (you can’t do this yourself), but we have to migrate all VM’s off 1 machine, call support, apply the fix, migrate VM’s from another host, call support, apply the fix, etc etc. We’ll wait for 6.7 U2, network engineer says issue is resolved in that update.
