Quality of Service ensures critical data is delivered consistently and pre-

dictably. EKI-6538 supports Layer 2 802.1p priority queue control to pri-

oritize network packets depending on customer’s needs. The feature of

QoS is useful in improving determinism.

sponding table of the packet default priority (0~7) and the switch

Queue(0~3). As WRR mode rule, each Queue will transmit packets as the

weight number (1~31) in turn.
