Traffic Prioritization

Traffic Prioritization includes 3 modes: port base, 802.1p/COS, and TOS/DSCP. By traffic

prioritization function, you can classify the traffic into four classes for differential network

application. IGS-3044GP(GC) series support 4 priority queues.

QoS policy

Traffic Prioritization interface

Label Description

QoS Mode Port-base: the output priority is determined by ingress port.

COS only: the output priority is determined by COS only.

TOS only: the output priority is determined by TOS only.

COS first: the output priority is determined by COS and TOS, but COS first.

TOS first: the output priority is determined by COS and TOS, but TOS first.

QoS policy Using the 8,4,2,1 weight fair queue scheme: the output queues will follow

8:4:2:1 ratio to transmit packets from the highest to lowest queue.

For example: 8 high queue packets, 4 middle queue packets, 2 low queue

packets, and the one lowest queue packets are transmitted in one turn.

Use the strict priority scheme: always the packets in higher queue will be

transmitted first until higher queue is empty.
