3.2.5 Port Mirroring

Port mirroring allows one port of the switch to monitor the traffic trans-

mitted/received by the other port of the switch. The network administra-

tor with a protocol analyzer is allowed to capture packets from mirror

port to evaluate and monitor without affecting the operation of clients on

the original port.

Enable the mirror function then start to setup the mirroring.

3.2.6 QoS (Quality of Service)

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.

Fig 3.26 shows the EKI-6538 QoS configuration page. Setting the corre-

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.

Warning Default Weight of Queue (0,1,2,3) = 1,2,4,8,

Higher priority queue weight cannot be smaller

than a lower one.
