    QoS

RUB

TECH

    The QoS(Quality Of Service) feature provides four internal queues to support
    four different classifications of traffic. High priority packet streams experience
    less delay inside the switch, which supports lower latency for certain delay-
    sensitive traffic. The GS-1208M could classify the packet as one of the four
    priorities according to 802.1p priority tag or DSCP. 

    This mechanism helps track network errors or abnormal packet transmission 
    without interrupting the flow of data. Allow ingress traffic to be monitored by a 
    single port that is defined as mirror capture port. The mirror capture port can 
    be any 10/100 port, 10/100/1000 port. Mirroring multiple ports is possible but
    can create congestion at the mirror capture port.

    To limit too many broadcast/multicast/unknown-unicast flooding in the 
    network, broadcast/multicast storm control is used to restrict excess traffic. 
    Threshold values are available to control the rate limit for each port. Packets 
    are discarded if the count exceeds the configured upper threshold.

We use SNMP Trap mechanism to inform supervisor to know the instant 

    abnormal status of the switch.

    Instead of using CLI interface, we provide a more convenient GUI for user. 
    We just need to configure switch via Web Browser. It is more quickly for user 
    to familiar with the method to control switch on the basis of this design.
