<p dir="auto">I have this issue with interface errors using pfsense to create a VLAN tag vs creating the VLAN Interface in vmware then assigning the Interface to pfsense.</p>
<p dir="auto">Scenario A:</p>
<p dir="auto">Create a VLAN tag in pfsense and assign it an interface and you will see after a while there's lots of out errors and I get packet loss about 4% on the interface and this causes issues on our network from time-to-time</p>
<p dir="auto">Scenario B:</p>
<p dir="auto">Create the VLAN on the vswitch in vmware then assign the new vswitch network adapter to pfsense, there's 0% packet loss and no out errors.</p>
<p dir="auto">I have to create more than 35 VLANS and vmware only supports 10 vswitch network interfaces per VM, I didn't want to create 4 pfsense VM to handle our network.</p>
<p dir="auto">I'm using VMXNET3 drivers and running 9000 MTU because we have 10Gbe network with the open-vm-tools package installed</p>
<p dir="auto">How can I get more details to trouble shoot this and is there any documented issues or solution/patch I can do to resolve this?</p>

<p dir="auto">I didn't try the e1000. I will give it a try and report back.</p>

<p dir="auto">Just out of curiosity, have you tried the e1000 emulated adapter? I know the performance won't be as good, but if it shows errors as well, that tells us something. Not sure what, but maybe it will help.</p>
