H3C layer-3 Switch configuration: analyzes VLAN code instances. Currently, there are a lot of people using layer-3 switches, and maintenance of switches has become a problem that cannot be ignored. Only the three-tier switch is configured, which not only saves your time and effort on accessing the Internet, but also br
The relationship between the transport layer and the network layer In the protocol stack, the transport layer is located on the network layer. The Transport Layer Protocol provides logi
In recent years, with the rapid development of internet/intranet and the wide application of B/S computing mode, the business of cross region and network has been growing rapidly, and the industry and users have deeply felt the bottleneck effect of traditional routers in the network. The three-layer switch can operate
Three-layer switch has a lot to learn, here we mainly introduce the three-layer switch intelligent flow processing technology. The popularization of computer networks and the expansion of application scope are changing our world, but also changing our thinking and life style. With the development of

With the popularization and deepening of the network application, the requirement of the two-layer switch is not only limited to the data forwarding performance, service quality (QoS) and so on, the network security idea is becoming the important reference content of the group netw
Layer-3 Switch Equipment is still quite common, So I studied how to identify the performance of layer-3 Switch Equipment. Here I will share with you, I hope it will be useful to you. With the gradual development of network applications, telecom-grade switches, especially
For example, simply using a vro, because of the limited number of interfaces and slow route forwarding speed, in general, in a network with a large volume of intranet data streams and requiring fast forwarding and response, for example, all three-layer switches are used for this work. As we all know, a router can connect to an enterprise LAN or a wide area network
The following describes the principles and functions of a layer-3 Switch. A temporary switching path is established between the initiator of a data frame and the Target receiver, it only has the ability to process IP layer or even higher layer data packets. Currently, most layer
automatically generated by the switch. After the vswitch analyzes the data packets, it automatically configures VLANs to automatically update VLAN members. The layer-3 switch can work in a network environment where IP addresses are allocated in DHCP (Dynamic Host Control Protocol. The www.2cto.com

Currently, most layer-3 switch devices in the market support link aggregation and Spanning Tree Protocols, which can effectively improve the overall network performance and meet more user needs. With the gradual development of network applications, telecom-grade switches, especially
router will be overwhelmed, and the router will become the bottleneck of the entire network.In this case, the third-layer exchange technology emerged. Generally speaking, it is a technology that combines routing and switching technologies into one. After the router routes the first data stream, a ing table between the MAC address and IP address is generated. When the same data flow passes again, this table is used directly from the second
In the previous two articles: Network virtualization flowvisor: Network virtual layer (top) and network virtualization Flowvisor: The network virtual layer (middle) respectively introduced the characteristics and implementation of
pinged by the core router are some, but there is no response packet. When we open debug ip icmp, we find that the Aggregation Router has a response, but the interface has not been sent out, replace it with ip route 0.0.0.0 0.0.0.0. It seems to be different from the forum post. Ip route 0.0.0.0 0.0.0.0 indicates that routes are enabled, and ip default-gateway is not enabled. However, after all, there is a difference in the mechanism between routers and switches. Www.2cto.com is configured with 3

The principle of layer-3 switching and the principle of DHCP are not explained here. Here we use a case to learn how to use layer-3 switching as a DHCP server and assign IP addresses to different network segments. In the production environment, it is common to use routers or switches as DHCP servers. Lab requirements: 1. Configure the DHCP service on SW1 to assi
