Often see network friends in the difference between the switch and router, in fact, if you have used both switch and router friends should know, for everyone, switch and router use the biggest difference is that the router can realize dial-up
The layer-4 switch actually adds the ability to identify the layer-4 protocol port in the layer-3 Switch, meeting more user needs and improving the performance. In recent years, with the popularization of G, 1g, or even 10g LAN.
The wide application
Layer-4 switches are quite common. So I studied the layer-4 switch technology and application. Here I will share it with you and hope it will be useful to you. With the increasing popularity of Mbit/s, Gbit/s, and even Mbit/s local area networks,
I. Lab Objectives

Measure the test taker's knowledge about how to configure VLAN routing for a layer-3 switch;
Layer-3
A layer-4 switch is a vswitch product developed through the layer-4 switch technology. A layer-4 switch is not so much a network device as a network management system. In recent years, with the popularization of Mbit/s, Gbit/s, and even Mbit/s, the
With the increasing popularity of Mbit/s, Gbit/s, and even Mbit/s local area networks, broadband MAN networks and even broadband wide area networks are widely used. Whether it is Intranet, exclusive, or residential intelligent networks, it is
Five, OpenFlow table
This section describes the components that make up the flow table and the group table, and also includes the mechanism of the flow table "matching" and "action" processing.
5.1 Pipeline processing Process
The switches that
Are you worried about the port mode of the switch? below, I will walk into the switch with you and hold the switch port mode completely. I will use an article with a picture and truth to make you no longer confused.
Yigu Switch
1. Switch Port mode
Mirror Port configurationMost switches support mirroring technology, which allows for easy troubleshooting of the switch. We call it "mirroring" or "Spanning". Mirroring is the copying of traffic from one port on the switch to the other (mirror port)
In a twinkling of an eye, IT has been mixed into this line for three years. IT seems boring, but I have never thought about what I want to do before. Why is IT boring? From my personal experience, I have worked in private enterprises and state-owned
In fact, the layer-4 switch is a network device, not a software network management system. It is mainly based on technology. In recent years, with the popularization of Mbit/s, Gbit/s, and even Mbit/s, the wide application of Broadband LAN and even
Layer-3 Switch configuration-configure a group of layer-2 ports

The current limits of vswitches and vrouters have been deprecated, and some products generally combine the two. For a wireless switch, its access method is wireless, and its role is the exchange function. However, its advantages improve the network
The rapid development of wireless networks brings about more expanded network space. In a wireless network, a large wireless network will certainly have a wireless switch, so let's analyze the outstanding advantages of the wireless switch function.
A repeater or hub cannot isolate a conflict domain and cannot isolate a broadcast domain, a bridge or a switch can only isolate a conflict domain from the broadcast domain, and the router can isolate the conflict domain and isolate the broadcast
In the complex network environment today, the switch has become indispensable, so the switch manufacturers also develop quickly, here to take Cisco to give us a simple exchange! Cisco: Cisco; A simple introduction: Cisco is the world's leading
1. Unplug the power cord of the vswitch, press the switch Mode button, and re-plug the power cord of the vswitch. Release the Mode button after the LEDs on Port 1x are off.
2. For the Catalyst 2940/2950 L series:
Unplug the power cord of the switch,
The backboard bandwidth in a Gigabit Switch mainly refers to the maximum data volume between the processor and the data bus. It should be said that it represents the comprehensive performance of the Gigabit Switch, which is one of the parameters we
