Hi,

Can we get some more info about the setup. Is it VGT, VST. Is it ESX to ESX traffic or VMs are involved? What is the ixgbe driver version you are using?

I use a Flow meter to create and send pkt in vminc5 or vmnic3 to test esxi network.

I use pktcap –uw –uplink on esxi to cap what I send.

And the topic is what I meet

Follow is what cap in vmnic3.vmnic5 is not ok - -!

damn it! I find I have set intel 82599 VF(esxcfg-module ixgbe -s max_vfs=4,4)! Now I close it and reboot(esxcfg-module ixgbe -s max_vfs=0,0),it work ok.But why open the 82599 VF can't recv vlan tag pkt,it's also a question!!

SR-IOV should not affect VLANs in the way you're describing. There are some limitations regarding VLAN filtering on 82599 cards but it should not impact you.

Have you tried newer drivers? There are 4.5.2 and 4.5.3 available on HCL

Some older versions had vLAN tagging issues, please update to the latest one.
