I just upgraded my lab ESXi and Vsphere appliance to 6.7U2 and since the upgrade I'm having an issue with my F5 load balancers.
I am using a standard Vswitch and have setup the port group to allow all vlans (4095) however the tagged traffic on the VM is not leaving the VM.
Even when running a tcpdump on the F5 on that interface, I don't see any traffic. I am not even able to see my standby F5 that is on the same port group, no l2 or l3 traffic will pass.
I have some other VMs on the same vlan (220) however the port group they are on is just for VLAN 220 and they all work fine. They can talk to each other but they cannot talk to the F5 which is on the same vswitch.
I also tried to create a new trunked port group with the same settings and moved the F5 to this port group with no luck.
Has anyone else run into this issue? Any other troubleshooting steps I can take?
I have a similar configuration ( a Vm with guest tagging enabled) and its able to ping to another VM with same guest vlan tag. The configuration is a newly deployed 67u2 configuration.
What was your previous vc and esxi version from where it was upgraded to 67u2? I am planning to upgrade some other deployment to 67u2.
Have you tried with any other VM with guest tagging enabled other than F5 load balancer vm ?
Don't have anything substantive to add other than confirm the same problem with two F5 pairs here. Fortunately, realised before having upgraded all esxi hosts so vmotioned the F5's over and they resumed working. Hopefully a fix is forthcoming soon
I am planning to upgrade 67u1 deployment to 67u2. I have normal linux VM with guest vlan tagging enabled. Have you seen this issue on all guest vlan tagged VM or only on F5 VM's?
I haven't tried with linux hosts yet, I'll give that a try... but from the sounds of it this may be a F5 issue?
My F5 VMs are using VMXNET 3 adapters.
Also I thought about upgrading the VM Hardware version from 14 -> 15 but this doesn't seem to work? It says the VMs are up to date at 14 however I can create new VMs with v15.
Anyone else notice that too?
I spun up a vanilla debian VM today and confirmed tagged vlan works fine. I used vmware hardware v10 to match my F5's. So seems like an F5 problem?
It looks like F5 VE is not supported for ESXi 6.7 U2 currently:
"ESXi 6.7 Update 2 is not currently supported."
Looks like F5 released a fix for it:
VE lost communication after upgrade to ESXi 6.7 Update 2
