Experts tell you what a layer-3 switch is.

high, but to support a large number of layer-3 protocols, such as IP, IPX, AppleTalk, DECnet, and so on, these protocols have different packaging formats, it is easy to implement with software, but it is very difficult to implement with hardware. There are too many protocols to implement forwarding with hardware, which will only bring about a sharp increase in costs. What is a

Test the layer-2 and layer-3 Performance of a 24-port full Gigabit Switch

Performance Tests on layer-2 and layer-3 vswitches with 24 ports and all-gigabit vswitches have encountered many problems recently. Experts have said that QoS ensures port congestion, high-priority data is processed first. It makes sense to improve the utilization of 24 fully-gigabit switches with insufficient bandwidth. Three-tier competition

Layer-3 Switch: Multiple forwarding of one route

Station B, because Station B and station A are not in the same subnet, station A will not encapsulate the destination MAC address of Station B in the Ethernet frame to be sent by Station. This is error 2. In addition, the layer-3 Switching Module receives the Ethernet frames sent from Station A to Station B. The
