XPe VLAN support?

[Mark K Vallevand]

I've looked all over for an answer. Maybe some has it here.

Is there a way to support virtual LANs (VLANs) on Windows and specifically
XPe?

We want to use the VLAN support (802.1.q) to make a single physical LAN
appear to be multiple virtual LANs to the upper protocol layers. This can
be fully supported in the adapter driver, or using an intermediate driver if
the adapter driver supports only part of the spec. My National MacPhyter II
DP83816 claims support for VLAN, but I can't see how its done.

Has anyone done anything like this?

The Short Answer: If you can do it in XPP, you can do it in XPE...
The VLAN accesibility should be a component of the NIC Manufacturer... I
have seen this done with XPP, and Intel Pro/100 LAN cards, but have not
attempted in XPE, but again if it's possible in XPP...

I don't have a Pro/100 on my XPe system, but one of our other XPP systems
has one. I don't see anything in the network configuration for the Pro/100
for enabling VLAN. Maybe I need a later driver.

You are most likely correct... the VLAN capability of the NIC is usually
contained in the Driver, or software package a particular MFR delivers with
the NIC. You can team, bridge and route adapters in XPP, but the core
functions of VLAN within a NIC are MFR dependant.

The Windows DDK has a sample VLAN mux driver. That turns out to work nicely
if your NIC driver supports enough of the VLAN stuff. And, unfortunately,
if your NIC card driver isn't good enough... BSOD.

If we need the DDK mux driver for our project, I'll try to upload the
componentized version to xpefiles.
