4.7.7 QoS Setup
The system support 2 level priority queues. The queue service rate is based
on the packet-based Weighted Round Robin algorithm. The ratio can be set
as 4:1, 8:1, 16:1, or strictly high priority first.
The port-based priority is to decide the packet priority by the receiving ports.
You can select the high priority ports from the switch graphic.
If TOS/DSCP based priority is enabled, it will be assigned to high priority
queue if the field value is:
expected forwarding: 0b101110;
assured forwarding: 0b001010, 0b010010, 0b011010, 0b100010
network control: 0b11x000
If 802.1p based priority is enabled, the packet forward priority is decided by
the CoS value. The high priority packets have the CoS value from 4 to 7.
In some situations, you may want the high priority packets to get forwarded
even the 802.3x flow control stop transmitting packets. In this case, enable
Adapted Flow Control will turn off 802.3x flow control for a short time to let
the high priority packets get forwarded. The 802.3x is re-enable when no
high priority frames are received for 1 to 2 seconds.
