It all depends... At least the cisco switches I have used have
protection by controlling on how large frames you can send, and
having automatic enlarging of frame size for VLAN Trunking port.
Of course those switches have some amounts of "jumbogram support"
as well at port by port basis.
So perhaps you can DoS your machine off the net (or your stream
very least), but not other machines.
