Class of Service Configuration (CoS)
Define CoS:

TCP or UDP- port number

IP TOS/DS

802.1p Priority Tag

802.1p Physical Tag

Select the require tag(s) and update.
The administrator can select the protocol that will be forwarded as the
specified mode. There are 3 administrator-defined UDP/TCP port
groups and many well-known TCP/UDP ports. The administrator-
defined port number may be a range or a specific number, depending
on the mask.
The operating theory for all 4 CoS types can be illustrated by the
following figure and table:
TCP/UDP CoS, IP TOS/DS, 802.1p are global setting for all ports and
has no relation with the physical port.
An example of the settings are:

Priority Mode: WRR. High weight=4; Low weight=2

TCP/UDP CoS: P2 FTP =>High queue; P5 SMTP => Low queue

TOS/DS setting:
P5 TOS 6’b010010=High queue; P2 TOS
6’b100010=Low queue

802.1p: P2 802.1p = 6(High queue); P5 802.1p =1(Low queue)

Physical port: P5=High queue; P2=Low queue
