In general, TOS support in routers is pretty easy, though it may not
be in Cisco's case depending on how they designed their fast switching
stuff. In theory, of course, Cisco is adding TOS support since they are
adding OSPF and TOS is a part of OSPF, but I don't know whether theory
matches practice in this case (it doesn't in the case of some other OSPF
Actually I was proposing that this be handled outside of setting TOS
bits, but I wasn't clear. basically if I own a router from cisco today
i can prioritize my interface traffic using the "priority-list" command.
i select by protocol. Could that concept be built on to give me per
port control over my routing in the future? who knows.
