4. Web Management selected: All Low Priority, All Normal Priority, All Medium Priority, or All High Priority. ¾ Port Number: When Custom is selected for Prioritize Traffic, you may assign specific Port Number for DSCP Configuration. ¾ DSCP Configuration: 64 kinds of priority traffic as mentioned above, user can set up any of Queue (low, normal, medium and high). In default, Priority 0~63 are mapping to Queue high. 4.4.
4. Web Management The loop detection is used to detect the presence of traffic. When switch receives packet’s (looping detection frame) MAC address the same as oneself from port, show Loop detection happens. The port will be locked when it received the looping detection frames. If you want to resume the locked port, please find out the looping path and take off the looping path, then select “Unlock port” and click on “Apply” to turn on the locked ports.
4. Web Management State: Show the status on the port. Protocol Enabled: Controls whether Loop Detection is enabled on this switch port. When Port No is chosen and enable port' s Loop detection, the port can detect loop happens and port will be Locked. If Loop did not happen, port maintains Unlocked. Unlock port: When ticking the port, port locked will be opened and turned into unlocked. If not ticking the port, Port maintains locked. 4.4.
4. Web Management will detect whether the broadcast packets received on the port still exceed the threshold. If the broadcast traffic is still higher than, the port will be closed for a period of time again. If the broadcast traffic is under the threshold, the port will re-open and forward the packets normally. Mode: Controls whether Broadcast Strom Protection is enabled (as a whole).
4. Web Management Packet Per Second: It is a threshold. When the broadcast packet traffic in a second is higher than the threshold configured, the Broadcast Strom Protection enable . Unlock Time: The period (in seconds) for which a port will be kept disabled in the event of a loop is detected (and the port action is to shut down the port). State: Show the status on the port. Protocol Enabled: Controls whether Broadcast Strom Protection is enabled on this switch port.
4. Web Management This function is used to configure SNMP settings, community name, trap host and public traps as well as the throttle of SNMP.
