Network scalability. Each member device in the stack system is able to process protocol packets - TP-Link T3700G-52TQ | T3700G-52TQUN V1 User Guide - Page 56
Each device in the stack system is called stack member. Each stack member processes services packets and plays a role which is either master or member in the stack system stacks merge into one stack because of stack link establishment, as shown in the following figure: Figure 5-4 Stack Merge 43 - TP-Link T3700G-52TQ | T3700G-52TQUN V1 User Guide - Page 57

You can configure LAG in two ways: • Static LAG: The member ports are manually added to the LAG. • LACP (Link Aggregation Control Protocol): The switch uses LACP to implement dynamic link aggregation and disaggregation by exchanging LACP packets with its partner. LACP extends the flexibility of - TP-Link T3700G-52TQ | T3700G-52TQUN V1 User Guide - Page 76
up to eight member ports. All the member ports share the traffic evenly. If an active link fails, the other active links share the traffic evenly. • One LACP LAG supports more than eight member ports, but at most eight of them can be active. Using LACP protocol, the switches negotiate parameters - TP-Link T3700G-52TQ | T3700G-52TQUN V1 User Guide - Page 77
, based on which the switch can choose the port to send the received packets. In this way, different data flows are forwarded on different physical links to implement load balancing. There are six options: • SRC MAC: The computation is based on the source MAC addresses of the packets. • DST MAC: The - TP-Link T3700G-52TQ | T3700G-52TQUN V1 User Guide - Page 78

interfaces in the same network segment would discover neighbors by sending Hello packets. If the interfaces are connected on the same public data link, and the area IDs, authentication information, network subnet, Hello data interval and neighbor router dead-interval are all matched, the two routers - TP-Link T3700G-52TQ | T3700G-52TQUN V1 User Guide - Page 218

The switch supports three schedule modes: SP, WRR and SP+WRR - TP-Link T3700G-52TQ | T3700G-52TQUN V1 User Guide - Page 310
, packets in all the queues are sent in order based on the weight value for each queue and every queue can be assured of a certain service time. The weight value indicates the occupied proportion of the resource. WRR queue overcomes the disadvantage of SP queue that the packets in the queues - TP-Link T3700G-52TQ | T3700G-52TQUN V1 User Guide - Page 311
