that only support IP Precedence. Since the DSCP first 3 bits define class
of service which maps to IP Precedence classes. When a device not
supporting DSCP receives a packet with DSCP marking, it will read the first 3
bits and treat the packet as if it was marked with IP
Precedence.</FONT></SPAN></DIV>

where "bigger-is worse" XXX000 should have a lower drop preference than
XXX010, XXX100, or XXX110. I don't know is this is how network devices
actually handle drop precedence is DCP.</FONT></SPAN></DIV>
