Priority Queue Index:
Provided 4 priority queues. MT800
will set the received traffic into one of 4 priority queues for
output. The packet with highest priority will be outputted
firstly. If this queue is empty, the next packet with highest
priority will be outputted, the rest may be deduced by
analogy.
z
Weight:
To set the weight value to the parameters of
selected application. The larger number of weight value is,
the higher priority it has.
z
Application Type:
Select the application type from pull
down menu, which include: Voice, Video, IGMP, and Data.
z
RTP:
Enter the start and end port number in the blank of
Voice Data Start/End Port
and
Video Data Start/End
Port
.
III.
TOS
ToS is an 8-bit field, and also the second field of header group in
IP packet. It is consist of two sub-fields: priority level sub-field and
service type sub-field. The priority level sub-field will assign the
priority for group within the queue. The group with higher priority will
be sent firstly.

IV.
DiffServ
DiffServ field was defined in RFC 2474 and 2475 that in order to
replace ToS field.
DiffServ integrated edge monitor & management,
assignment and service priority. DiffServ provide different service
priority to different requirement of QoS, in order to meet the
requirement of different service.

V.
802.1p
The label of 802.1p specified 8 settings of priority weight form 0
(Lowest) to 7 (Highest). MT800 will determine the priority queue of
traffic according to these labs of priority weight.

VI.
VLAN Tag
VLAN Tag is a hexadecimal number, which added to the packet
that transmitted in VLAN. The VLAN Tag is to indicate which VLAN is
the packet belongs to. Thus, the packet with the specified Tag will be
transmitted in prior while it was received by MT800.
