QoS
CoS
Enable CoS—Set quality of service by creating a VLAN ID and a QoS priority. The 
priority is from 0-7, where 7 is the highest. The default is 4. Remember to also make 
all QoS settings on your switch.
DSCP
Enable DiffServ— Differentiated Services (DiffServ) is based on packet marking 
and queuing disciplines. The marking is done by adding a field to the IP header, 
called the DSCP (Differentiated Services Codepoint). This is a 6-bit field that 
provides 64 different class IDs.
DSCP Priority Value—Describes a particular service level in terms of bandwidth, 
queueing theory, and dropping (discarding the packet) decisions. Network 
packets are classified according to their DSCP value and are given a particular 
forwarding treatment; for example, the bandwidth required to reserve for the 
packet. The range is from 0 to 63.
