is is possible to pxe boot (a la as the first step in a cobbler install) when a system is hooked into a spanned switch port?
I guess my question is can the pxe process somehow be made aware of vlan tags coming in and use one of them?
Any reason to not have the default VLAN be the one you PXE boot from?
If so, some systems (e.g. IBM UEFI-based systems) can handle PXE booting from a VLAN.
