Press clear will clear all counters 5 Trunk setting This page is used to set trunk group for load balance and auto backup The smart switch supports two trunk group each trunk consists of 2 4 ports Trunk hash algorithm can be selected according to 4 different methods Port ID Among the trunk member ports the packet will be distributed based on the port ID SA Among the trunk member ports the packet will be distributed based on the source MAC address DA Among the trunk member ports the packet will be distributed based on the destination MAC address DA amp S A Among the trunk member ports the packet will be distributed based on the XOR calculation result of the source MAC address and the destination MAC address 6 QoS setting 6 1 Priority mode This page allows the user to set the scheduling mode for the TX packets at each port All high before low Strict priority All packets will be assigned to either high priority queue Queue 2 or low priority queue queue 1 The packet will not forwarded until the high priority queue is empty WRR mode There are 4 priority queues for Weighted and round robin W RR mode When this mode is selected the traffic will be forwarded according to the number set in each queue The queue ID has nothing to do with the priority Example lf Q1 Q4 are set to 5 3 2 8 then the traffic at the specific port will go out in the following sequence 8 packets stored in queue 4 2 pack
