QoS, or Quality of Service, ensures that camera video packets are prioritized in a
network. QoS in the network optimizes network performance by classifying traffic
types and assigning network resources based on the traffic classes. The
Cisco VC 220 camera offers two QoS modes: 802.1p CoS and DSCP.

CoS
•
Enable CoS— Class of Service (CoS) specifies data packet priority based
on the 802.1p QoS value in the VLAN priority tag of the packet. This feature
is disabled by default. To enable CoS mode, check the box.

is disabled by default. To enable CoS mode, check the box.
•
VLAN ID—Enter the VLAN ID (1 to 4095) in the field provided.
•
Priority—Set priority to a value between 0 and 7. The highest priority value
is 7. The default CoS Priority value is 4 (video), which matches the Cisco
Small Business Smart and Managed Switch QoS settings.

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. The default is
34.
