Cisco Small Business Administration Guide for the Model PVC300 PTZ Internet Camera with Audio and PoE

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.

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.
