vlan is an attribute of a particular "network address group" -- for
instance, in my office, right now I have a 10Mbps and a 100Mbps wire.
I have two since I exist on two networks.
I could just as well get each of these over the same wire, with
virtual lan tagging. I'd envision something like this:
# ifconfig fxp0
media: Ethernet autoselect (100baseTX full-duplex)
# ifconfig fxp0:0
inet 220.127.116.11 netmask 0xffffffe0 broadcast 18.104.22.168
# ifconfig fxp0:2
inet 192.168.42.1 netmask 0xfffffff0 broadcast 192.168.42.15
What syntax/architecture do the big routers and/or other OSs use for
multiple-interfaces-as-one and vlan tagging?
