NimbostratusVE lost communication after upgrade to ESXi 6.7 Update 2
After upgrade ESXi 6.7 from build 13004448 (last public patch before Update 2) to 13006603 (Update 2), VE 14.1.0.3 lost communication on TMM interfaces (mgmt worked fine).
I did some research then. Egress traffic from TMM went correctly (another VM could see it), but ingress traffic did not fall into TMM. Tried to send burst of 10k broadcast ARP requests in VLAN with TMM interfaces connected, but with no adequate change in stats (tmsh show net interface all-properties raw) on TMM interfaces (stats of mgmt interface, connected to the same VLAN, are increased adequately).
Restarting VE did not help. Restarting ESXi did not help.
After rolling the ESXi back to the previous build, everything started to work. Tried once again upgrade to 6.7u2 and rollback, with the same results.
Speculation: Since Update 2 release notes mention bugfix in vmxnet3, this may be related. AFAIK, TMM takes care of interfaces by itself (in linux, these are visible in lspci, but neither in ifconfig, ip link nor /sys/class/net/), so there could have been made some change in host-side vmxnet3 that is not yet reflected in TMM code.
Has anyone similar experience with ESXi 6.7u2?
Best regards,

AndréYes, we are experiencing the same issue. We have opened a ticket with the F5 support, but no results yet.
Ondrej_Holas_69Same symptoms with Big IP VE v13 and ESXi 6.7u2 mentioned in another thread:

dexterous_38891I am seeing the same issue here with both 14.0 and 14.1. I wish I would have seen this thread earlier instead of troubleshooting the issue for three days!
this is due to a change ESXi6.7 U2 has, here is a workaround from BIG-IP side to make this work (until ESXi fixes it later) https://support.f5.com/csp/article/K74921042

We have applied the workaround and we can confirm that it's working as expected.
