Hello,
Is it necessary to have a VLAN capable NIC in order to have a linux box
participate in a VLAN, or can 802.11q be entirely emulated in sofware
at the driver level?
The following thread almost answered the question, but it is still not
quite clear to me:
http://groups.google.com/group/comp.os.linux.networking/browse_thread/thread/bbbe30a3f12f62a8/1f7f8c22e9b56c9e?lnk=gst&q=VLAN&rnum=8#1f7f8c22e9b56c9e
It depends on what you want to do.
If you want the Linux machine to be the VLAN switch, then VLAN switching
is done in software. vconfig can do this for Linux, although I've never
played with it myself. (vconfig is distributed with Fedora, at least,
and possibly others.)
If you just want the Linux machine to be on a VLAN, then the whole
purpose of VLANs is that they are LANs. Nothing but the switch knows
that the LAN is virtual.
You can also connect the Linux machine to a VLAN switch on a VLAN trunk
and define multiple virtual interfaces on the Linux machine to make the
the machine effectively multihomed even if it only has a single physical
interface.
In no case is the hardware 802.11q-aware.
