Tagged VLAN 1

@Derelict, you are screaming... Please tell me why?

[johnpoz]

And again.. If vlan 1 is native and default which is almost always is.. Since its the default vlan it would be untagged.

There is ZERO reason to tag vlan 1 as you have it designed. That its working is telling me the hyper-v setting is stripping it so pfsense sees it as untagged. Or it wouldn't work.

Depending on tagged VLAN 1 will cause you grief from now until forever because vendors do not agree on how that should be handled.

In your position I would fix Hyper-V to understand that VLAN 1 is the untagged, default VLAN.

Or I would cease using VLAN 1 with Hyper-V.

Sorry guys, I do not understand it completely. Are you guys saying I should not use VLAN1 (default) at all? Because when I set port 1 in VLAN1 to Untagged, port 1 on VLAN10 will automatically switch to Exclude! When I create an additional VLAN20, then I am able to set port 1 for VLAN10 and 20 to Untagged. Could you please en light me here?

You can use vlan 1 all you want as native untagged vlan - this is the default vlan on all switches.. But you wouldn't tag it..

Please post the output of
Get-VMnetworkAdaptersVlan

And the exact setup of pfsense.. Do you have more than 1 vm interface in pfsense? What vswitches is it connected too.. You have different types of vswitches in hyper-v.. Do I really need to fire that crap they call hyper-v back up? ;)

You can use any vlans you want on your switch for your connections to pfsense.. Does not have to be vlan 1..

Derelicts point is you almost never vlan 1 tagged... Why do you think you should tagg it in your switch if you set it as native (or untagged) in your vswitch settings? And how do you have it setup in pfsense.. I you do not have it tagged in pfsense, and you don't have it tagged in your vswitch... Why would you tag it on your physical switch?

Sorry Johnpoz, I don't understand. On the HP switch I only can both vlans set to tagged. When I set vlan1 to untagged, vlan10 is set to exclude...

The output results of Get-VMNetworkAdapterVlan ;
This is the LAN interface of the pfSense box.

My setup of pfsense box;

Both interfaces are Hyper-V virtual switches.

Hope this helps? Let me know if you need more input.

As far as I know, the HP switches were derived from Brocade.

On the Brocade, if you wish to mix tagged and untagged traffic on a switch port you would set the port to dual-mode.

If you want the PVID to be the default VLAN 1, you would do this:

# vlan 223
#  tagged eth 1/1/6
# int eth 1/1/6
#  dual-mode

VLAN 1 is now the untagged PVID and 223 is tagged

If you want the PVID to be other than VLAN 1, you would do this:

# vlan 223
#  tagged eth 1/1/6
# vlan 224
#  tagged eth 1/1/6
# int eth 1/1/6
#  dual-mode 224

VLAN 224 is now the untagged PVID and 223 is tagged.

Both configurations assume a starting point of eth 1/1/6 being a member of only the default VLAN 1.

This is an example of why mixing tagged and untagged traffic on an interface always contains disclaimers stating that different vendors handle things in different ways there.

As an aside, adding ports, tagged or untagged, to VLAN 1 is not allowed at all on that switch. A port is a member of untagged VLAN 1 if it is not a member of any other VLAN, or if dual-mode is set as in example 1 above. As far as I know there is no way to tag VLAN 1 at all.

Hi Derelict,

Thaks for your input. Please have patience with me. I am not a guru like you guys. I wish to have all that knowledge!

This is how I configured the HP switch.

What port are we talking about?

Port 1 is connected to the LAN interface of the pfSense. Is that what you mean?

[Derelict]

So set VLAN 1 on port 1 to Untagged.
