QoS Policy
By setting the
QoS
policy, you can assign a higher/lower priority (based on your
configuration) to received packets to pass through this device. You can define some
policies which classify received packets based on source/destination IP, MAC, port and
protocol type. This feature is useful when the WAN link is very busy or congested or when
using special applications that need real time services such as Internet phone, video
conference...etc.

•
Policy Name

types of address: IP address and MAC address. By default,
the IP address is 0.0.0.0 for all IP Addresses but the MAC
address is 00-00-00-00-00-00 which cannot be used to
classify.
Port and Protocol Type defines all packets for special
applications.
•
Protocol Type
– The field defines traffic packet type, i.e. IP,
TCP and UDP.
•
Priority Queue
