Issue/Introduction

Symptoms:
  • When pinging from a virtual machine (or from a vmkernel adapter) in a VLAN tagged portgroup, the ping response may return into ESXi (through the pNic) without a VLAN tag
  • Running the pktcap-uw command displays entries similar to:

    #pktcap-uw --capture Drop --srcip 10.1.100.10
    The session capture point is Drop
    The session filter source IP address is 10.1.100.10
    No server port specifed, select 5710 as the port
    Output the packet info to console.
    Local CID 2
    Listen on port 5710
    Accept...Vsock connection from port 1025 cid 2
    19:31:54.848571[1] Captured at Drop point, Drop Reason 'VlanTag Mismatch'. Drop Function 'NetPollWorldCallback'. TSO not enabled, Checksum not offloaded and verified, length 62.

  • If you are using an Intel X710 nic, when you run the esxcli software vib list | grep -i i40 command, you see entries similar to:

    #esxcli software vib list | grep -i i40
    net-i40e 1.4.28-1OEM.550.0.0.1331820 Intel VMwareCertified 2017-03-17
    i40en 1.1.0-1vmw.650.0.0.4564106 VMW VMwareCertified 2017-03-17
  • Running the esxcli network nic get -n vmnic0 command, you confirm that the older i40en (1.1.0) driver is used instead of the newer net-i40e (1.4.28) driver similar to:

    #esxcli network nic get -n vmnic0
